Thorns in tree mode will be handy I guess, but doesnt really effect me much. For ppl with low mana regen it would help.
Revitalise will now replenish with WG hmmm interesting... Works best on rouges/Dks/Cat druids...
Would be OP on the meelee groups that is for sure. Still not sure If I would spec into it as I would need to give up Seed hehe. Maybe something to look into? I just know that the maths is not good for any mana based class; (50/50 on rage classes) and is realy just good for energy users.
