343I should use things that have worked well in the past (we all know what they are, so surely they should too) and that the majority of people have liked. You're never going to please everyone, so you have to go for the majority. In saying that,
The sprint animation isn't needed to give the feeling of speed at all, we all know this, I'm sorry but we do. There are countless games out there that do this and not just FPS either. Can the sprint animation do this? Yes, but it also causes a lot of other issues in halo (maybe not in other games as they are different) that ultimately changes how Halo feels and more importantly plays. Then, countless amounts of time (and money) is spent trying to figure out how to fix these issues that the sprint animation has brought. When in reality we already know the solution to it. Let's be honest here, since the sprint animation has come into Halo it has been the cause of so many other issues in the game and that people have had it's not even funny. Everything from map/level design, to weapon/grenade strengths, to how weapons should work, the melee system, and so on...it's a big trickle effect. It is to the biggest most debated things in Halo....but I still think as long as people don't feel "slow and sluggish" ultimately most people will not care if the sprint animation is in or not. The sprint animation doesn't sell games, the game being fun does.
Clamber I understand the problems with it, but feel it's impact could be minimal if any still if done right and that mainly will involve things like map design around it. If it becomes too difficult to do, then get rid of it.
ADS zooming should 100% go as it literally brings nothing to the game and practically no one asked for it. The old style system should come back but revamped graphically. It could look absolutely incredible all the while
distinguishing itself from other FPS.
Thrusters I'll admit I didn't like at first, but I think most people are like me and don't mind how they were implemented by 343I in Halo 5. I also think they could be a key component in the game in combination with things like equipment/AAs whatever you want in....speaking of which,
Things like Spartan charge, Ground pound etc should be AAs or equipment or something like this that are one time uses that can be used anytime. I feel like when you start the match your character should feel "basic" per se. You then go around the map to pick up items, weapons ect. (AAs, equipment whatever you want) to make your character more powerful. Doing this falls in line with a Arena gameplay I think. Power ups (like OS, Invis. Speed boost and new ones etc) should be used as soon as you get them like they always have been (love the fact 343I added that you can kill them before the Spartan puts it into their chest) Then there could be combinations with equipment and/or either with weapons and/or equipment with and/or even with power up and so on. If you want to go that route which I think is worth exploring. Like if you have speed boost and the equipment/AA (or whatever you want to call them) of Spartan charge, it makes Spartan charge become more powerful aka do more damage, sound familiar? Well it's not a bad idea I thought but most people hated it in Halo 5. Why? I think mainly because you can constantly Spartan charge... but if you can't constantly do it, I don't think people will hate it anywhere near as much, if at all. That can also be applied to AA's even back in Halo Reach / 4 days. You could do many different combinations here, use your imagination. I think people know what I'm getting at here, so I won't go into it futher. I'll gladly throw out some more ideas if people want though. I've heard some pretty good ones out there before.
I'm sure the majority would be ok with things like this because items are 1 time uses. Equipment in Halo 3 showed that majority of people were okay with 1 time use equipment. When Halo Reach first showed it had jetpacks at E3 (I remember it like it was yesterday), the majority of people were freaking out, as in loving the idea, But ultimately most people didn't like it because they were practically limitless. Things like Jetpacks weren't the problem though I think, it's how they were implemented that most people had a problem with and then ultimately they ended up hating things like AAs in general. Again, if the jetpack was a one-time use item I think it'd be a hell of a lot more accepted.
Again, just think of how many things you could make... combinations you could do with equipment/AAs all while keeping that Halo gameplay intacted. Honestly, it's pretty endless. Best part of all this.... Since these things are pick up items, they could be removed, disabled, turned off ect. very easily for MLG / HCS playlists if people want. Also, lot of this stuff and even more things could be used in modes like firefight (which should be a huge focus by the way in the next Halo game and there should definitely be a ODST style FF for sure!)
By doing this I feel 343I are now making a game that everything can be used (if people want) in every aspect of the game. Campaign, multiplayer, Forge, firefight and so forth. There is none of this debate of "Sprint should be in campaign maybe but not in multiplayer or vice a versa" or, "there should be a few playlists that don't use the sprint animation and/or Spartan abilities", or "armor abilities are great and should be brought back but how do you use them" and so on...it's all gone. I'm not saying there won't be any problems in the game as I'm sure there will be but I think there will be a heck of a lot less. I think doing this at your core is a pretty good compromise between old and new players and would fix a lot of issues that people have had with the last x amount of halo games.
I just know that something needs to be done with Halo and I think taking some of the better elements from the past and present games is the answer, especially from the past. Halo not very popular anymore, heck I've said to people "I'm playing Halo tonight" and they've asked me what is that game about... That's so sad... it's sales are way down compared to other Halo games and just in general, it's not very big in the competitive or mainstream scene which I know some of you say I don't care about that but here's the thing, you should care.... a lot!!! because ultimately those things leads to sales and if the game isn't selling, good bets are that game or franchise won't be around then much longer. That might sound crazy but it's true. One could easily make the case too that Halo isn't the face of Xbox anymore and that is a sad... SAD.... situation.
I hope Halo 6 is the best Halo game to date and puts it back into the spotlight again :) oh and, sorry for the long post, I tend to do this from time to time lol
