No one should want 'cool gear' in LFR sets because the lead art designers made it obvious from the start for most the sets now, 'Not the mythic set? Not the real set.'
You can tell with shit like the Warrior set that they just built the awesome set for the smallest portion of the population when it's current and then handicapped them down for the heroic/normal sets. Fuck that, that's actually the worst shit to me about all the armor set decisions in WoD. I didn't mind the exclusive colors and I was one of those 'smallest portions' for it. I wouldn't even mind a few bells and whistles for the mythic version but the mythic versions of tier look like the proper brand and the non look like your dollar store power ranger equivalent.
It was nice to get tier sets in LFR in pandaria. Kept me playing for months to get sets with a few characters.
WoD just did everything wrong in terms of rewarding players that are not doing normal raiding. No emlems, no fun reputations, no good rewards in heroic dungeons, it's all just the daily login farmville game or grind. Why did nobody at Blizzard saw that players want to actually do something in the world, trade with other players for their profession, farm things out the in the world for your profession, etc.
To me whole WoD felt like they took all the half-completed features of Titan (social game aspects, just doing casual stuff instead of playing) and just build a WoW expansion out of it, instead of throwing them in the trash where they belong.
Also the jump from LFR to Normal was way too hard! I could casually do normal raids with twinks in wotlk and pandaria. In WoD the LFR is just faceroll, while you can just do 2-3 bosses on Normal with LFR equip, because if only 1-2 person fail the fight is over. If you have 4 difficulties just balance them right, that you have a curve to progress further.
e.g. the beastmaster boss, it's near impossible on Normal with random groups if you dont have a some damage dealers with way better equip than you get there
