It's annoying. No disrespect to elitists but this isn't about what is hard and what is not, it's not really that hard to be honest, just cumbersome and not that fun. "Put that thing there so you get more dps duuuuuude". OK, it's nothing too impressive or hard but where is the pew pew?
When I first saw it in MoP being introduced I immediately thought that's going to annoy so many people. Returning to the class now I'm honestly surprised it stayed in. I learned how to use it in 10 seconds and frankly it's easy in most fights to manage but it's still not fun.
So I wonder, do people really find it fun?
