As it is currently, what BLU can improve on?

Tank CDs generally need to not be a cast. This is especially true of Chelonian Gate and Diamondback,as their use already has an inverted cast time of being stuck doing nothing, and Force Field for being a coin flip on it doing anything in the first place.

I agree. Some folks think that mitigators being so clunky to use is part of the "skill" of the tanking Blue Mage, but I strongly disagree. Diamondback, fine because it's such an OP invuln, but the others defnitely need to have no cast time in the Tanking Mimicry because putting a high skill threshold there simply raises the skill floor in a basic aspect of tanking (mitigating tankbusters) and kind of turns people away from the role.

If you don't remember these old fight's timelines, you'll defnitely have a hard time and put more pressure on your healer.

I was also kind of bummed by Force Field. It's extremely unreliable in the situations we'd need it the most.
