Best Tank for Scoundrel Team

Mainly for heist and galactic war.
I think a big part of it is ocd. He's the only light side character on my scoundrel team.

STH, grind that boy up, Chewie and GG are garbage

If you can spare the Arena tokens, you're not likely to regret farming STH. My personal opinion is that as a tank, he blows those other two out of the water. On top of that, he has a secondary purpose as a Rebel tank.

What makes STH a better Tank? Is it the turn meter gains alone?
On paper GG looks better. Expose, damage over time, similar starting speed, and much more starting health.

STHan is miles better then chewy or GG. For a significant amount of time the meta was basically who's STHan went first won.

Like everyone said, get STH, I still use him and I finish in top 50

STH is still found in the end game. Deffo STH
