Hate on LFR is really overrated.
I really avoid LFR and just dont think about that.
I've got a colleague who plays WoW only for current quest-lore-content, he completes every possible quest/main-lore campaign, does LFR and then unsub before next patch. He's happy to play like that.
He's a casual who wants to know more about Warcraft, who are we to say such people doesnt really deserve to play the game that way?
