Who is the best underrated toon when fully geared and maxed?

Ima-Gun Di: Good health and protection, good special, and killer against droids. Oh, and he self heals for three turns when he is hit with a critical. That's just on a regular team...put him under an Anakin lead and he is great in the arena. Under a Barriss team in GW, he's almost unkillable.

my staple is Imagundi and Aayla there amazing jedi.

Dengar...he allows you to complete a huge portion of the T7 rancor without needing to farm Empire characters for otherwise useless potency mods
