Because it's a much more favorable stat now, right...? Last time I checked, Sub, the one spec that did care about crit, no longer does. Assassination has never cared for crit, nor did the removal of Cold Blood increase its value past the "worst secondary stat"-threshold. If they truly wanted to increase the value of crit, why didn't they simply address the actual issue?
They need to decrease the value of the other secondary stats if crit is to become useful, or introduce new mechanics that propel its value past that of haste and mastery. Alternatively, they could finally just normalize energy regeneration, and make it independent instead of relying on haste; that would bump down the value of haste by quite a bit. Either way, the removal of Cold Blood resulted in NOTHING.
Are the people responsible for rogues even sentient!?
