Even with balance issues I still think it's a lot of fun.
To really play it as it's meant to be played I think you'd need to coherent 16 or 32 person teams on both sides, with voice com. They'd have to be broken down into squads of four with at least a couple people coordinating the collective efforts of the group. That'd be most realistic probably.
I've been having a lot of fun with it. So much so that I've blown through about $700 in the last 24 hours just so I can make some system upgrades.
