The sit mechanic to force crits persisted throughout all of vanilla wow and for 3 years now. If this was abuse of a bug, Blizzard would have changed it and it wouldn't have been this way for 3 years already. Why the sudden change of heart to go non-Blizzlike on the issue? If this was a bug, exploit, or abuse of an unintended mechanic, then Blizzard would have changed it when they ran Vanilla WoW, but they did not. There are plenty of genuine bugs and exploits that have gone unaddressed for a long time that have affected many players, but a nerf (not a fix) is suddenly needed?
