I have to really disagree with OP. Having played wow for almost 10 years as a tank, the way the role has evolved is in a very good place. The only game I find tanking to be more fun to play is Tera which has quite a unique gameplay aspect to it. The thing with Wow tanking (Especially Paladin and Death Knight) is that besides your basic cooldowns you have main rotation abilities that you can use however you want to provide healing/damage reduction when needed. You don't just mindlessly cycle through your rotation at progression content, but rather set up the use of your abilities such as Death Strike and Shield of Righteousness towards specific boss abilities. It feels like you have much more control of your own survival, rather than just hitting CDs when you get low. If you remember back when threat was a factor in Wow, it was up to the DPS to watch it. Tanks abilities were quite limited, so if the DPS pulled the boss even for a few seconds it was them not paying attention. FF threat is not like this, the tanks should be able to have control of it in most situations rather easily. The pulls are the only thing that require effort if your DPS are stupid.

Tanking should be about survival and using your abilities accordingly to reduce damage, that is what makes Wow and Tera tanking quite enjoyable. I don't mind threat being a factor, but currently tanking in this game is just too simple with the real hard job falling to the healer.
