If, when we win , it would reset our cooldowns as a reward, it would make this bearable. Try facing 3 teams of vader/sid/dooku/kylo in a row like I had tonight. My healers were unable to cope with this. I've a pretty decent roster of gear 7 units so that wasn't the issue.
As much as I enjoy a good challenge, taking 2 hours+ of trial and error on this was just the complete opposite definition of fun. Plus, 0 blue ability mat drop on node 1-11. Could not finish 12. Frothing rage.
