I know that blind gives resolve per second as the poster above me said. To explain my issue with the CCing; the issue is that you can chain too much CC into a combo.
Mezz/Blind to catch up with your foe and give a positional advantage over your opponent (which is uncounterable ATM), throw in 1 free DOT for example, followed by another when blind is broken, stun them, they will use Resolve because else they'll die, continue to burst them. If they run you slow them or relocate them.
So we have 1-2-3-4 CC in a combo for some classes, 1 of them is counterable, the others are not. The biggest issue is that Blind/Mezz even though it gives Resolve per/s leaves you CCed so long that even if you chose your battle correctly you still will be zerged, stunned again and dead.
1 blind /mezz = very often 100% dead toon
Feel free to continue discuss this cause I'm always open to different opinions but ATM my opinion of this is that blind/mezz is the same as a stun, it works a little different but its the same result and when you can chain a mezz/blind into a stun then you suddenly have 2 free stuns followed by slows and relocation, that is indeed powerful and something that not many classes should have
