First I didn't agree with the cyclone nerf (general nerf) but after sitting in CC 90% of the time versus a druid and warrior I got kinda frustrated. Though my partner wasn't really... let's say... skilled... so he didn't stop most CCs, but still I couldn't do that much.
Personally, I believe the CC's need to be more globalized in DR.
For instance: CC's such as Cyclone, Poly, Fear, etc should all share DR. The spammable ones.
Stuns should all share DR with each other. There really is too much CC. Some of it is stoppable and some isn't realistically stoppable. Thankfulyl, some of it is getting nerfed. I hope they look at it closely for 5.2 though.
Also, globalized DR = bad. Less spammable/instant CC = good.
If nearly all CC's share the same DR, CC chains would be a thing of the past which would drastically reduce skillcap. Comps like MLS, RMP, thugcleave, Talbadar cleave - all work because of the CC chains that can be put on the healers. (and they have crazy burst)
