We have the Felguard Axe Toss and the CC component of Hand of Gul'dan to remedy that issue. Also, the general change to length of fights will counteract how badly one interrupt can completely screw you. Despite the depressingly long cast time of Hand of Gul'dan, this is all very, very promising.
The only problem with Affliction, which has a fantastic kit for pvp and pve, was target switching... which is largely fixed with Soul Swap. I think a lot of people knocking this ability haven't seen the Glyph of Soul Swap, which allows you to retain your DoTs on the original target.
