I'm always amazed at how many bad tanks there are in this game... I have to admit, initially I didn't understand why people couldn't grasp the idea of hate management. The thing is though, playing FFXI for years as a THF made me really adept at hate management (the best THFs worked hand-in-hand with the tank to keep hate bounced exactly where it should be) and I'm assuming made me much more receptive to playing effectively as a tank... not everyone entering FFXIV has that advantage... so OP's guide will be a helpful first step for them.
