But yeah, I miss manual fairy-ing quite a bit. Heck, probably even including have to make it dodge things.
I honestly have no idea how the system functioned, but what I do remember is that if you were max level and killed mobs for low level players they would get no exp, even if you weren't in their party.
With flash however you could keep everything aggrod to you while the low level players killed them and they still got the exp.
