I don't mind the dps nerf, becuase we get CC in the form of hex. And Hexed mobs don't heal like poly'd ones do!

Hex150 Mana 20 yd range
1.5 sec cast 45 sec cooldown

Transforms the enemy into a frog. While hexed, the target cannot attack or cast spells. Damage caused may interrupt the effect. Lasts 30 sec. Only one target can be hexed at a time. Only works on Humanoids and Beasts.

Note the word "may" there - which means its a chance to break on damage like fear.

Cheers,
