Least time to 50

[Poetic]

This is fast xp and it works fine, but with low cha and low int due to lack of gear those root recasts and charm breaks really burn more mana than you expect. That's why you dont just charm 1 mob into 2-4 mobs, root the rest, and break charm and kill over and over. Thats super fast and efficient if you have the mana to sustain it, which you wont.

I agree though, this is certainly the best way to solo as an enchanter, but this is no exploit.
