In no particular order:
AAs to be left in, assuming little problems are fixed. I don’t understand why people complain so much–most complaints (except for AL) have to do with “competetive” players saying that “casual” gamers are too good with them. That doesn’t make any sense–what a REAL competetive gamer wants is a challenge, and here is your challenge. Things like jetpack merely add another dimension to combat. I don’t see why people complain; worst comes to worst, grab your own Jetpack.
AL is another story and needs to be rebalanced. Frosting must be completely removed, and any number of other changes could be tried, such as shortening the total length (although if this was implemented, I would suggest a reduction in recharge time), removing the EMP except for vehicles (or vice-versa), blah blah blah. Any number of things could be tweaked with any AA, but I would highly recommend custom settings so that they could be changed by the community after launch.
A return to Halo 3’s lighting style (not system itself). Reach made the system very accurate–the reflections look great in terms of where the reflection is in relation to the light source. H3’s style looked amazing in terms of brilliance of glare–light reflected off of any shiny surface, and it looked great and realistic. Just climb aboard the belly of a Scarab and proceed up to the deck–you’re blinded at first. This is how a game should be.
A return to previous Halos’ color tones. Let’s face it, Bungie tried to make Reach serious and in result we got annoying grunts instead of hilarious ones and a very boring color tone. I can’t stand it anymore, the Forge blocks aren’t the only things that just say BLAH.
Forge 3.0. I want to pull out all the stops, whether they make sense or not–they don’t need to make sense, this is the Halo community we’re talking about. We make chess, skeeball, and hockey. We want more!
I don’t understand why some vehicles, like the civilian and campaign versions of Falcons–the code is already in the game. (Don’t get me wrong, I know nothing about coding, it just seems like it shouldn’t be that hard to port them from campaing to multiplayer). There have been some great Forge threads in the forums, and not one suggestion is a bad one.
I mentioned this earlier–but ENGLISH-SPEAKING ENEMIES!! At least IWHBYD should make them speak English.
Vehicle balance fixed. A DMR should not be able to kill a fully shielded anything.
