If used very very sparingly, I think its ok. And there is something to having it used to test a tanks reaction skill. However, I find it to be used far too often and is a bit too gimicky if you ask me. Being a tank this game sort of makes me feel worthless. Maybe I am too old school? But as a tank I already have to deal with the fact that I cant truly protect my allies no matter if I have enmity or not, due to SE's fascination with spamming AoE's and environmental traps. At a certain point its just insult to injury when you tack on mobs that use hate reset (particularly if its more than once).

My ideal vision of a tank would be a class (and battle conditions) that could keep hate with the proper amount of skill and gear. But doesnt have too worry about gimmicks like hate reset. Now if Im not skilled enough to keep hate, or if a BLM or DD is just going crazy w/o any regards to the consequences, then you deserve to have hate all over the place. As far as traps, Id rather they be focussed only on person with most hate (ideally the tank) so as a tank I can feel like Im protecting my party. With AoEs SE still hasnt managed to do a proper job of balance between ranged and melee in my opinion. So either they need to toghen up melees to be able t take a bit of damage or they need to dial back AoE spams quite a bit

BTW, this isnt a "it cant be done that way it works now" argument, this is a "I do not like the way it works right now" argument. Just personal preference, but in older MMOs I played If I held hate it mattered moreand meant more.
