firstly one thing i think the game needs is a battlefield 2142 style commander and squads(or lances) the ability to direct simple orders and basic powers(supply/ammo drop,radar scan, turret drop and maybe even thunder lrm barrage[thats mines])
also thinkin of a server side bank , if the cash generated by fighting and kills is reduced by 25%, but now there is a bank you can deposit cash in (using the player donate system) you have to donate before you die or you lose everything, and the bank takes 20% upon depositing (you deposit 10k you bank 8k) if you dont bank it you dont save it
if any of you have ever played megamek you will know where im going with this 3rd idea, in megamek you ,after solaris training. join a house befor every fight you declare your intentions are to take a piticular planet, the outcome of the fight decides a 1-8% change in the overall percentage of alignment of the entire planet and thus affects a galactic map and the overall controll of the various houses and clans. im not sure the best way to implament this but megamek has it pretty good
1V1? ,1V1V1 or even 4 ways..........personally i find 2 way team fights a bit boring any chance of getting a map or game type that has more than 2 teams nothing like seeing 2 teams duke it out and jumping in and tearing it up with your own 1 man team!
king of the hill style map type/game type, there is a becon/dropship or factory in a certin location with valuable intel/ancient tech time spent near it generates points per-person for that team, objective is hold the location and slug it out for precious points
