Most people define private server class balance as in "you did not mess up with the official game too much" in case of low rate or "you made changes to balance things out" in terms of high rate. Low rate doesn't need balancing, that's Gravity's job.
Monkey: we will not make changes to gravity's classes such as making extended on par with trans or make all trans class have equal popularity, there's some of every class in the game, each has their strength and weakness, and some people enjoy playing each. I see pallies and clown, gypsies too, there are a lot of them, I really don't understand what you don't like about our class balance, maybe you just don't like Gravity's balance or have played other server that were very different before, most servers (98%+ I'd say) have more sinx than pally, it doesn't mean it's completely unbalanced.
