Retri paladin in 4.0.x (4.1.x too?) had Divine storm doing low dmg (compared to TV) and did cost 3HP! Blizz decided to change that cuz it was rly an "unused" spell to what we have now (6s cd, making HP instead of costing). As we look on MoP atm, divine strom is back to the point of 4.0.x (low dmg 3 hp cost). Didint blizz learn anything from cata? it wasnt so long ago...
