Tanks are perfectly like they are.

Its the best balance between Tanks in ages.
if you actually think they are balanced, could you explain how? dps? they may do similar damage on paper, but in the field, this is incorrect. defense? gnb and warrior have way more cds than pld and dark. take dark in lower 69 and below content, they have nothing. healing? war has equilibrium on a 60s cd. it can be buffed by 20% for 10s, but it is only ONE CAST and NF needs a target. pld can use requiscat and clemency 5x with a buff of 50% and can hallowed ground during it. drk has AD and needs many targets to make it worth it. gunbreaker only has aurora. in leveling content, pld doesnt need a healer. they can solo dungeons/bosses. i have witnessed it.i can do it.

Doesn't matter if one tank does as much/ a bit more DPS you can clear all content as well as the current savage with whatever tank you choose to play, it just all depends on what you like.
just because jobs can clear content doesnt mean they are good. pld in heavensward could clear creator savage, but it needed a LOT of gear padding to do it. yes, strong jobs like blm or sam can clear content, if they know what they are doing, but other utility jobs NEED to be good at their job to do this, too. they need to try HARDER. it takes more EFFORT. that is the problem with your rebuttal. if another tank has to struggle more just to clear than another tank, then they are not fine. and it isnt just based on what you like. if you need a clear, you play what you NEED to.
