I'm not sure a Dodge tank is especially feasible in a game with a LOT of AoE magic... but what you want is a Rogue, I think, with Parry Master and lots of Finesse (assuming that boosts dodge tank).
I'm not even sure Regular tank is feasible without a Taunt which bypasses armor.
It's not "awful dev balancing" just because the game isn't designed for your specific class preference.
