Is Stormtrooper viable for Empire Teams in arena?

Stormtrooper's expose comes in clutch. His defense bonus combined with crit immunity from shoretrooper, makes one of the thickest wall for the empire. you should try go up against those teams if there is any in your shard

Unless opponent has a Thrawn it's very tough to get past the double taunt. But you know everyone has Thrawn and with CLS JTR it's not invincible.
But I'd say shore+storm is the best tank combo at least for empire teams
