Persistent player bank accounts (tracked across servers like unlocks and rank are in BF2142), would fix this. Then people wouldn't buy Mechs unless they're sure that it's the most cost-effective option. Like, if your wallet is persistent, and you always buy a Mech, you'd go broke. The smart player would only buy a 'Mech if he's sure he can earn enough money to pay it off and make a profit, either through kills or through winning the round. And if the other team is completely loaded and your team is dirt-poor, then you don't focus on winning, but on losing as slowly as possible.

What do you guys think?

The problem with persistant stats is that it put new players at a major disadvantage. It futher encourages trophy hunting which isn't what Battletech is about. Finally, Crysis isn't set up for persistant stats and implementing them is hugely time consuming while we're on a tight time budget. Doing them half way makes cheating much easier so if we decide to put them in, it won't be for the initial release.

How does it put new players at a disadvantage? I thought infantry was going to be kind of balanced against the expensive vehicles?

I understand, but I still think it would make the game cooler and more fun, even if it has to wait to be included in an update.
