Copied from Katalana :) : The mana usage is being rolled, and there will be more discussion of how to make spells more expensive.

Well patch was and is disaster for all mana using classes, so it would like to encourage all lower lvl players with such class to reroll to non-mana using classes if they feel game is too hard for them now. Non casting classes are: Warrior, Scout, Rogue. Then whisper someone from guild for re-invite.
