Someone's nostalgia-ing too hardHere's my take.
I have played since vanilla. I, as a vanilla player, positively LOVE the revamps to old content to make it viable for max levels.
The sad part is that most people who complain about "omg they're rehashing content QQQ" probably didn't even do the content when it was viable in the first place. What surprises me most is the "omg it's ony and nef again". Really. It's Nefarion again? All over? Where's my class call, then? Or his fear? Wait, he's not doing either? And I don't need an Onyxia Scale Cloak for the fight? I thought this was just rehashed content? And Onyxia doesn't Deep Breath? Or summon whelps? Where's this rehash content at again?
There's a HUGE difference, people, in "rehashed content" and "returning characters". That's all the Nefarion encounter is, a returning character. That's all the Ragnaros encounter is, a returning character. That's all ZA and ZG are. Returning characters. Hell, heroic Deadmines only had ONE returning character in it in the first place (Cookie). The only real "rehash" of that is the map is the same. Oh noes, Blizzard is running out of ideas! CLEARLY!!!
Jesus, people. You get a great game with fun and exciting encounters, and what do you do. Complain about it. Stop being whiny brats. Go make your own game if you think you can do better. Oh wait. You can't do better. Nobody can.
Quit if you want to over this, but I'll see the rest of you with some sensibility in ZA and ZG. Which will be fun as hell.
