I'm running Revan and I was beating Revan squads with Traya before his event returned the second time. I literally never had a problem with Jolee's mass revive.
How can you take out two toons before targetting Jolee? The only solution to this problem is fixing terrible strategy.
The fact that jedis under Revan can heal themselves back to full health from a red bar is powerful. Mass assists and cleanse makes them hold their ground on defense. But mass revive? If you give the opponent's Jolee the chance to revive more than one toon then the only thing not working correctly is your method, not the opposing toons'abilities.
