It would be nice if there was one day to pick what map you want to play and the match type. It would help out players that never get the level they need for "ive seen it all" achievement. And the developers see which maps are liked the most.
Would also be nice if they returned the campaign mission select screen. I've been playing with my friend and he's been trying to win the first mission as IMC, yet we only end up on other missions and on the off chance that we do get The Refuelling Raid, we're militia. I don't know why they took that out...
How about map voting like Halo? The lobby chooses which maps they want to play with votes, or they can choose none of the above and get more maps to vote on.
