My three biggest problems with Halo 4 mm are:
1- joining "in progress" games
I hate joining games like CTF at 4-0 and they have the flag half way back already, there is no point.
2- vehicles aren't even
The ghost is waaaay too strong and is a ***** to take out. I know how easy it is (plasma pistol then plasma grenade) but doing that at a ghost while the rest of their team fires at you is almost impossible. And the warthog and mongoose are almost useless. They are too easy to destroy and the gunners are practically ohk's
3- guns need to be more equal
The dmr is the strongest, followed by the BR, followed far behind by the AR. This is wrong, they should all be bore equal, not in bullet strength, but the dmr kills in four-five shots and takes 4-5 seconds whereas the AR takes a whole clip and takes like 8 seconds, the times should be more equal to allow players to use their preferred weapon with out being destroyed by other players.
