Instance server is full

YEEE 3.2 is here and also the instances are full after 1 hour trying to enter in a instance nothing i cant go in if i try like 2 times i get the DC i think it was the worst idea that blizzard had ever tried give Conquest badges on heroic dungeons and dont buy new servers to put more people thanks blizzard to make me pay 13euros for nothing. I dont know how much blizzard earns per month, and I dont care, I just want blizzard to when they do this stupid thing please increase the sieze of the servers...
Its funny to give opurtunity to everyone to play endgame but wait a minute WE CANT GO INSIDE.
Sorry for my bad english and please do something
