Got it on first try today for the first time too. The Key was to put a zeta on Finn and some speed on Poe (204, not too great but good enough as I didn't want to sacrifice potency). ZR2 helps a lot too. Feels great to give Dooku the beating he deserves. Now I can't wait for the event to refresh so I can crush that annoying fool once again ^^
Team Resistance is such a great and useful team... While I was at it I 3-starred LS9-A with the same team and wonder if I can go further on these LS9 nodes...
