GMY Mythic Event T3

Old ben lead is the easiest if you have sub -g11 jedi. His leader gives evasion, and TM on evade, which can shorten the initial onslaught. One GMY grants Tenacity Up, it's just a matter of taking them down. My kill order was Maul, Nih, Dooku, and finally Sid, and then mop up sith trooper/assassin in whatever order they fell.
I used Old ben lead, GMY (2*zeta), Ani, ahsoka, GK. I also beat it previously without any zetas on GMY, though it took more tries.
