PvP battles would be awesome. Would need some balancing (Omnipotent Pylonic? Hell Nope.) But it would have some potential to be highly competitive and fun.

We've had it before. Then it died in some server crash.

Would be fun, not sure why everyone is so worried about balancing it. Tiers make it pretty obvious if it's a bad idea. If you wanna pit your T1 against my T12, then that's all on you. ;]

i think this could get so messy so quick. what if one user logs off in the middle of the battle to avoid losing?

i can hear the potential forum topic tirades from hear, can't you?

I agree with Gray that tiers would make it easily balanceable, and nonetheless people would throw fits. Ohhh, I can imagine the drama after some egos being wounded and then claiming that it was unfair. No thank you.

We need this! Friendly direct competition is wonderful and I imagine the user base would come up with there own way to balance it to make it fun.
