After running the new dungeon (so no problems with "established tanking patterns") I actually hate this change even more.

With no offense meant, but anyone who feels it's an "improvement", or that it "feels the same" must have just tried to tank on WAR as if it were any of the other three tank classes without actually attempting to play to its strengths.

This circle-shape really is only an improvement to those that want to level all jobs without really learning anything new, and if that's the basis on which jobs are being changed...
