I like the idea of teams.
Btw, if you limit HP in 1vs1 you almost should do the same to Linker since they can stall nearly just as long as any priest can if played right :s
I'm for allowing them, because some priests and linkers are amazingly tactical and have great ways to actually kill you.
Um that's about all I have for now, I agree with the entry fee too, its like betting on yourself to win and it will make it easier on you guys to host without having to dig too deeply in your own pockets.
