It's kind of funny to see all the people who hate on 343 have similar complaints throughout the forums, that are usually just either because they get outplayed in a certain way because of one of the Spartan Abilities, they don't get their "Easy-To-Splaser" Falcon, or that automatic weapons are becoming useful. Don't get me wrong, this game has its flaws, ie: the campaign (partially loved it, partially was disappointed, like awkward sex), grenade spamming, Achilles Farming, and lack of permanent social playlists, but that doesn't mean that 343 is doing this to mess with us.
I get that some "hardcore" Halo fans (people who played at least one of the classic halo games) don't like the innovations Halo has added to the gameplay, but it doesn't destroy the franchise, in fact, a lot of die hard Halo fans, myself included, actually enjoy the gameplay because it diversifies the different ways to play halo. It's not like how it was in the classic Halo where you were either a bullet sponge or a One Man Spartan Army, the balancing in this game is so good that you can actually be terrible, but still be useful to your team. With Warzone, you don't have to kill spartans/bosses, capture bases and destroy cores to be useful, (unless you just keep dying every 9 seconds, respawn is 8). If you're not good at capping bases, you could distract/kill enemy spartans trying to defend bases. You have shittish REQs so your attacks are weak on bosses? Kill enemies shooting the boss so your team can kill it, or kill enemies with good REQs and use them on the Boss or incoming enemy Spartans. Not good at attacking/hunting for kills? Just stay back and defend the base so your team can focus on capping bases or killing bosses.
In this new generation of Halo, you don't have to be a powerhouse to win, (though it does help) you can actually be decent and win games. I remember playing Halo 3 on the 360 and just getting mad because I'd always end up facing a team with a powerhouse sniper who was virtually untouchable. But now, with thrusters sprint and REQs, you have a fighting chance to minimize a powerplayer's usefulness.
Though there are a few things about Halo 5 i don't like (mainly Arena based) I think that it is overall a pretty solid game. I get that some people, (quite a bit), don't like the game and that's perfectly fine, I've seen almost the same thing growing up with Halo throughout the years, (nothing this bad since Reach), so I know there will be criticism about the newest Halo game, especially with Bungee abandoning it for a less successful idea. but there has never, nor will there ever be, a Halo game that could ultimately kill the series. This series is too big to fail, (movie reference), and there are too many people invested into the series to just bail just because a game did not live up to their standards, (considering that the bar for Halo is unrealistically high), instead, the community would rise up and prevent another screw up by providing necessary feedback, (especially considering how drastic the change from 4 to 5 was), just like the community has done thus far.
Though I may not agree with your opinion, I appreciate that you took the time out of your day to vividly and emotionally (mean this in a good way, not the 8 year-old that rage quits every match that starts 3-4) express your disappointment so that the feedback can help fix and balance the gameplay and mold future Halo titles in a way that satisfies both classic and new fans alike.
We're not out of this yet, we can still *loses 348-1000* destroy the enemy core!
