Great work but we all know something that involves team work won't work in places like LFR or LFD. Raid wipe mechanics or more then using 2-3 extraordinary abilities like stun/interrupt/cc is going to be to hard. We have also seen that it doesn't work when Blizzard tries to make things harder. They are now at this point in game that everything has to be easier and easier (I am not talking just about content but pet battle entry fee, grinding reps etc.). If they release LFR harder then DS LFR was you can expect major nerfs within few weeks.
In theory it should be like this, but this is just romantic view. I know many people with children, work and not much amount of free time and they are successful raiders. Not world first or crowd who can kill things without debuff but they can down heroic bosses in just 2 days with 3h per day. LFR, unfortunately, has become AFK ground with players are not willing to learn anythingLFR aint for noobs, its for raiders who cant commit to a guild anymore beacuase of RL. And with LFR they can que for it anytime they want and get a good raiding experience. You know raiding = wiping = learning = killing the boss, not going there facerolling everything and geting free epics. DS LFR was crap, ive seen sometimes 5-10 people afk in it.
P.S. Do I need to say it's my opinion?
