People are disgusted by polyspam, but it only exists because our damage outside of orb-nova-storm is so fucking shit.
If our frostbolts wouldnt actually get outhealed by every DPS' class passive healing, you wouldn't see poly spam.
Bullshit. Polyspam exists because it means teams can't do anything when you're waiting on DRs on the enemy healer. This is a side-effect of Blizzard fucking up the dispel system in MOP and has existed since MOP.
