Making bases destroyable (MP)
Also it would be cool to see individual reputations... for instance, instead of just having factions, each player could have a certain rep. ; and for instance have a bounty on his head, so that if i.e. Player1 has a bounty on him, any player could take a mission to destroy him, get a reward, and tractor his ass to prison... or something...
Anyway, the main issue, I'd like HP on the bigger things, the outposts, etc. ; I wouldn't care if they were rebuilt every ingame 5 hours or so... but just the oppurtunity to blast a Rheinland warship into small bits would be really cool.
