Increased Holy Thunder Blade cooldown to 10s from 2, reduced aggro gain to 3% from 5%.
Besides, i dont think this is a good idea either. This skill allowed us to generate our aggro faster on a target. Other tank classes have higher aggro than knight class. And with this change, knight tank lost its method to generate high aggro on single target.
maybe you missunderstand that skill like many others.
this skill is only a taunt. you cannot "generate aggro" with it, unless you are even not the #1 in aggro list. only if anyone else has way more aggro than you, this skill should be needed anyways, because the "5% aggro generation" was not your aggro multiplier on your character. it is instead like this: "your actual aggro on the mob will be increased by 5%". in other words, it was only suitable to use it as a taunt (which it is in fact) and not to "generate" aggro :O
