Try leveling with no heirlooms and mop rares are dangerous. Most have 1 shot mechanics as well. Challenge modes replaced heroics and LFR is a joke but its for people who don't have the time to raid. If you find LFR easy raid normal modes. You haven't even done half of what the game offer and yet you still say it's easy.

Lfr isn't beating the game and getting a full set of epic pvp gear isn't beating the game. Completing throne of thunder on heroic and achieving gladiator still mean something. Their still is exclusive content mounts, titles, achievements and a special boss.
