Best jedi tank could be...

Jaceousprime

General kenobi.

Saber slam...deal physical damage to an enemy and inflict disadvantage for 1 turn. Which prohibits that enemy from scoring a critical hit.
Spring the trap... taunt for 3 turns and if this ability is dispelled all allies gain retribution and offensive up for 2 turns..
Strong with the force.. general kenobi gains 12% protection for each jedi on the battlefield.

Like the idea. However, giving both retribution and offense up may be a bit OP. But it would make "buff immunity" become pretty important.

It makes them.decide weather tk kill.him first or dispelled it lol.
