The only thing they fucked up in Wrath was the amount of time we had ICC without anything else interesting.
No, there were other problems. PvP was totally borked at the beginning (remember when even the honor blue items required a minimum rating to purchase?) The rating system malfunctioned very badly as all the low end players just dropped out. Wintergrasp was a server-crashing disaster until they limited usage, and tenacity never really worked well. Oh, and in order to try to fix PvP problems, they ended T8 prematurely so they could roll out... IoC! Ulduar sacrificed just so they could happily release that battleground.
