Well, I originally posted this in Matchmaking, but snickerdoodle suggested that I post it here.
First off, I'd like to take a moment to thank 343 for putting in the time to keep updating Action Sack every now and then. When Halo 4 first came out, I thought it would largely be ignored, which would've made me sad since it was my favorite playlist in Halo: Reach. So, thankfully, 343 has (mostly) lived up to my hopes in regards to the Sack of Action.
Now, for the issues. One of the biggest issues is Husky Raid. It shows up on the vote way too often and it gets voted way too often. This wouldn't be a problem if the map selected for it was actually good. The map promotes heavy camping on your team's flag and getting kills, rather than going for the flag. If each team has any sort of player that has any semblance of skill, the match will go nowhere. The vast majority of my matches on Husky Raid, along with many other players I know, have ended in ties. Ultimately, Husky Raid ends up being a complete waste of time. Now, I know that winning isn't everything, but it's really annoying when I can't win simply because of the map and/or my teammates wanting to get kills, rather than push for the flag.
My easy suggestion is to simply remove Husky Raid from Matchmaking, but I also believe that the gametype could do much better on a more efficient map, as in a non-narrow hall map. My second issue comes from a lack of more variety within Action Sack. At this point, there are two gametypes with random weapons (Husky Raid and Fiesta, a gametype with only plasma pistols, a lesser version of Splockets, and mini-slayer. I'm pretty sure there's another option or two, but I can't think of them off the top of my head simply because they're not that memorable or because I'm not sure if they're still in Action Sack since I just never see them, such as Binary Slayer.
So, here's the thing, 343. Currently, Halo 4's Action Sack is just inferior to the Action Sack of Halo: Reach. Reach had much more variety and had totally unique game types, such as Hotshot, Hog Potato, Hockey, Halo Ball, Dino Blasters and BOOM! Ball. And that's not even mentioning the less unique ones, such as Shotgun Assault, Shotty Snipes, and Splockets (which is superior to Rock and Rail). For Halo 4's Sack of Action to really thrive, it needs more diversity. It needs less of things like Husky Raid and more things like Hotshot, Dino Blasters (would now have to be Spartan Blasters), and Hog Potato. Bringing back Assault so that we could have Shotgun Assault again would be a nice plus. But, while you're at it, you might as well just bring back Action Sack to Halo: Reach.
In all honesty, removing Action Sack was the final nail in Reach's coffin for me. After removing Anniversary BTB and Squad Slayer, Action Sack was all that was left for me on Reach. You had a good thing going for you, 343, but you killed it. You made Reach so much more fun by improving on what Bungie had built, but you took it all away when you really didn't need to. Action Sack is by no means THE core experience of Halo, but I believe it to be an integral part since Bungie introduced it in Halo 3. Action Sack just allows players to experience the wackiness of Halo. It's a time to take a break from the more serious/competitive playlists and to just have a good time. However, I just don't feel that relaxation that I seek when I go into it on Halo 4 due to the lack of diversity that Action Sack truly needs.
So, please, 343, work on Action Sack. Preferably, it'd mean a lot to many players if you could bring it back to Reach (even though you've declared in the past to never touch Reach again), but it would also mean a lot if you could improve Action Sack on Halo 4 before the next Halo comes out. My suggestion would be to start by taking the gametypes of rotational playlists and inserting them into Action Sack. I believe that this would be a vast improvement and would make the playlist more popular.
If anyone from 343 actually took the time to read all of that, then I thank you for your time.
