I don't need to lose any important survival talents yet I can still spec quite far into ret tree. High dps means I can also get snap agro and hold it immediately. Not only that, I still see well-geared tanks struggling with threat, atleast when it comes to mages and destruction locks pulling insane amounts of TPS.
That being said, the OP should definitely learn more about tanks if he is going to come and complain about how we spend our talents. Or go back and cry in the corner, just like before.
