I’m not sure about drain as opener in order to get Annihilate down as fast as possible. Drain + Basic gets the same reduction as Basic + Drain. But you leave DN open to Ability Block for 1 more turn. Anyway, stunning all 5 with EP happens once in a blue moon, so I think opening with Drain is definitely the best option.
Let me finish with something else.
Yesterday, I played against an almost mirror team (EP, DV, DN, Thrawn, ST). My DV was faster and debuffed the lot of them. My finger was hovering above the CB button, but then their DN drained and suddenly CB was on cooldown. It went downhill from there.
I don’t understand how DN could have got a turn before DV. DV definitely got off more than 4 debuffs which means under EP, he’s back at 100% turn. That means he moves instantly unless the enemy DN also had 100% and it’s random. I didn’t check the enemy DN’s speed before the game, but the only explanation I can think of is that somehow their DN was equally fast as DV which is pretty spectacular considering DV gets speed buffs from his team.
Is there another explanation?
