i hope they give arance an instantspell that does not clear ab debuff, atm any kind of movement is 100%dps loss as an arcane mage..
and i hope the make haste shorten the duration of lb or mby that lb will explode if the affected target dies.
and as for frost i guess some pvp oriented ability simular to teh spiritwalkers grace,
and with all healing classes getting defensive dispelling mages need a new cc, polymorph sucks now and it will suck even harder in cataclysm.
