That said, TBC was miles better, PvE wise, which also includes interesting Lore. I also don't get why someone on the first page said Magtheridon required insane class stacking, did you even progress on him? TBC kept getting more and more interesting tbh, you were really looking forward to the next raid WHILE still enjoying the current one.
Who here actually wants to set a foot into ToT anymore? Imo one of the most bland huge instances ever made devoid of any wow-atmosphere. Bosses aren't all that memorable because almost all of them have nothing to do with Lei-shen and are just thrown randomly in there, like turtles, beast-heads, a snail, a bird . really -_-. Which is how this expansion feels for me, way too random because they just lack a proper backstory. Heroic modes are not the only PvE aspect and I'd say not one of the most important ones. The most important one is the atmosphere in the raidinstances, no matter which difficulty and this is were MoP really drops the ball.
(If you want another example, they made this awesome HoF design, made us quest thru all the dread wastes with the Klaxxi, huge quests with epic questline ending, we go in to kill Empress, Empress dies and all we get is "haha lol come see me in terrace kthxbye" from the Sha. No Roleplay, no klaxxi thanking you, no cool cutscene, nothing. This killed that instance for me.)
