While I cannot comment on how the event is for Empire Users. I can say that my team was able to auto Tier 1 and still have most of its protection. Tier 2 I am not able to auto but it is still relatively easy. I ended all three runs with at least 2 players with full protection and normally have to use the defend ability only on 88 as he is super duper squishy (even though I just got him to G9!). All in all I love the event as it finally is rewarding my commitment to the droids and I tip my cap to the devs as this is a great event. Good luck to all of you droid or empire users I hope you have the same success as me.
