World of warcraft pallys?

i think pallys are Way overpowered... they get to wear plate, be invincible for 6 sec, heal, stun, have great mele and ranged damage. So its like fighting 2 warriors with mele and range.(2 because once you get them to 1hp they bubble heal). Oh by the way if you think stunlock rogues are cheap our best cheap shot lasts 6 seconds and we have to get 5 combo points to do it. pally just clicks a on.
