Hi. I run ewok elder in arena. I posted a screenshot of my normal arena team right now but I ran out of tries from the 6pm snipefest. The thing that ewok elder does the best is create a second kill on sight target for your enemy. If they kill my FOTP, well, he's coming back to life. With additional heals to follow with daka and luminara. He has about 3600 power at level 60 as a 4 *, heals for about the same as daka (slightly less because my daka is 5*). But, his heal can revive. His heal does remove debuffs....with some bugs that are being addressed by the developers apparently. One thing is that the healing immunity is not classified as a debuff in the game yet so it doesn't clear, secondly, it doesn't clear all debuffs, just one. On this same note, ewok elders heal will heal through a healing immunity debuff which makes up for the removal not working (kind of, but I usually use it as a debuff clear). His direct revive has an 8 turn cooldown. That's plenty imo considering how much energy my guys have when they revive. The AI usually bursts down the guy I revive, so it's nice to run a character like stormtrooper han alongside ewok elder, to taunt, then revive (if I'm that lucky). It's not perfect but ewok elder is literally on every arena comp I build. He's just too strong of a utility character to leave on the bench.
