Blu Tank is too weak I think.

DPS is the middle ground.

Healer is busted. You do a whole lot with little effort.

Pairing Basic Instinct with Healer Mimicry is the go to for the Permanent Sprint + 100% increased damage and heals + spells can't be interrupted and no damage penalty.

Really nice. I think Blu does some really competent DPS in their burst windows. It's only really Tanking that Blu falls short because you have to play the Tanking game with knowing the fight since every Tank CD or skill has a cast bar. A problem the other tanks don't have.

If they want to balance things I'd suggest that players can have their own builds for Party Finder shenanigan's but for Duty Finder and main story content I feel the devs should put together Tank/DPS/Healer sets that they feel would make it balanced for everyone.

With the DPS sets everyone runs if they squish the damage you can put them on par with the other classes. Blu is mostly burst windows and then a filler spell.

But hey time will tell.
