Please show me an Armory link of your Twilight Vanquisher main.

"- Blizzard has underdelivered on a heavily-hyped expansion in virtually every way."

Really? Every way? No, they really haven't. Almost all builds of all classes are far better than they've ever been, prot warriors in particular being nothing short of a masterpiece. Questing is much more varied and interesting than ever before, the game looks and sounds amazingly better. The reputation from tabards system means never having to grind dungeons you hate. Every profession now has a viable way to make money.

"- Blizzard has made the "end-game" into nothing more than a walkthrough of a 3D environment."

Look, any goober could be easily carried through everything in TBC except for the latter half of Sunwell. This is the equivalent of T4 content. It's not meant to be hard. This game is not made for the minority of hardcore Sunwell raiders, but there are encounters for them even this early in the game. If you want cop out and say Sarth 3D is a "pointless" achievement, then you're just a giant hypocrite. What were warglaives, other than a visible "I cleared endgame" marker? Same with Twilight Vanquisher/of the Nightfall.

I'd wager to say "The Immortal" is a better testament to the value of you as a player and that of your guild than any amount of TBC epics were.
