I used to be hardcore raider like crazy and i couldnt wait till new raid day. But with intriduction of LFR, normals and other crap what pretty much showed you whole raiding contetnt for free killed it for me. My motivation jump into mythic is gone, becouse progress same bosses over and over just to get better itemlvl gear is boring. I want to be harder content also unique in term of bosses and enviroment not just better loot. I want agian to feel that i am killing THE BOSS no just his more powerfull version.
Not to mention that releasing 7 bosses for launch is joke. Like WTF. Compare this to TBC or Cata. Our guild killed last boss of 1. tier in Cata week befor Firelands patch so we never have been bored with the game. Where is my motivation to raid? For me it isnt worth. I will rahter check everything in LFR or normal then play some other games what actualy reward me with more content to explore then just give me boosted version of same over again.
