Don't get me wrong, ret NEEDS inquisition, and not just for the damage buff. I couldn't imagine how jaded the spec would be if all you had to do was spam TV. Infact I wish I had to inquisition more often. But I do wish it could do some damage when I hit the button, or at the very least have a cool shiny effect... If I cant damage my enemy at least I can bedazzle them.
After playing a monk most of this expansion, they are forced to keep up a buff and debuff... and its fun to do. The most important debuff for a monk is tied to their strongest attack, why cant inquisition be as rewarding as that?
Now you might say "well rogues and feral druids have to keep up a lame buff", and your right... they do. But let me ask you.. how many rogues and ferals have you seen in pve? No one plays them as far as I can tell, and those that do I commend you. I mean, rogues have been the least represented class for how long?
I know I am not max level, and maybe in time I will learn to love refreshing inquisition and seeing that lil glow at my feet. But right now I feel I have to refresh it every mob I go to, only to have half of it go away as I run to the next one. Whenever I hit inquisition I just go "ugh"... like I will literally look at my computer and just say "ugh" and make a face.
TLDR: Inquisition needs more zazziness. It needs an effect that makes me smile as I unleash its fury on a unsuspecting gnome. Make me want to click it and not just have too. And this is all my opinion.
