Does this spells the end of leechers?

That's why they're unbalanced.

Rather than AM/Bishops being responsible for most of the killing, they should be brought down closer to the expense/training speed of other classes, and higher level and better exp maps need to come out so training doesn't become ridiculously slow.

And AMs would be in line for a few new bossing skills. Unless you're going to say that they don't deserve to boss either.
