Hey guys. You know every class doesn't need 5000 different types of ccs right? Remember when some classes didn't have interrupts? It will be ok.
While it's absolutely true that classes don't need to have 5000 different cc types as you put it, I think that WOD has pretty much shown that some cc needs to be removed from some classes and some should be added into others. A class doesn't need to have much cc indeed, if it can be used correctly. Remember that this is also the main reason people were complaining about not being able to ''outplay'' their opponents.
For instance, Paladins (all specs) currently have only 1 cc, which is via a talent. Talking about Fist of Justice. You have the opportunity to spec into the other choices as well, but we all know you drag your team down by doing so - at least in most case scenarios. Having only 1 cc which is strong, yet predictable also makes your gameplay a bit boring. I believe it would be much more fun if Ret and Prot had baseline Blinding Light while Holy could have Repentance.
In the end, I don't know if I am sure about how good Legion changes will be, but I don't think that Ferals - or any other melee with a hardcasted cc - was the main problem here.
EDIT: Fixed my first paragraph, as it could have been interpreted wrong.
EDIT 2: Not qq'ing about Pala here, since it's my main class though it's easier to bring it as an example.
