You transform into a colossus for 24 sec, breaking all roots and snares and increasing your damage dealt by 20%.
Now lets nerf/change the rest of the broken stuff :
psyfiend
generation of shadoworbs
frostbomb
cold snap
symbiosys
DISC PRIEST
generation of holy power for ret
generation of FoF procs for mages
second wind
resto shamman mastery
blood fear
howling blast
obliterate
monks (as a whole?)
life swap for spriest
displacer beast
shock wave
warrior fear
application of affli dots
kiting for kite classes
uhm, thats it for a split second, theres probably waaaay more that needs to be fixed
regards
Edit:
Deaths advance
blinding light
instants for holy paladins
stance dance for warriors
weapon switches
shs for rogues
bear stun in all druid forms
more to come ...
