I'm lvl 5x and I've never used a bot. =)
The real problem is when you play alone, it's boring but I play with my brothers and some good friends that I've made in there.
Most of them used to be botters but now they play more with me and I don't judge them, I respect everyone's will.
I think the real problem of iSRO is the community behind, not all of them, but the racist. They make you hate the game so much that you want to lvl up to kick their butts.
