Dodge everything?

I am having a dodge ball nightmare today. Lost my first Arena match of the day (wanted to try my new 6* RP out) due to dodges all over the place. Now I am in a slog fest of a GW due to dodging and AI giving crazy assist rates and damage.

I'm facing a basically cookie cutter team of Phasma (L), Sid, Lumi, Dooku, Daka. Level 63 (Dooku) to 66 (Daka). They are shredding apart both of my Arena teams that are level 69-70. I one shot Dooku, Daka revives. I try on Daka, dodge. Try Sid, dodge. Try Dooku again, dodge. Meanwhile Dooku who is level 63, BLUE gear is getting double crits of 3000?! If he isnt going 3-4 times in a row with Phasma assists 80% of the time then he is double stunning my team. Phasma called a VM, Daka assists stunning one, Dooku goes next stunning two. So 3 out of 5 are stunned on my side.

I've been working with 10 different toons now swapping them around for well over an hour and I still cant kill them without taking way too much damage than should be "normal" for a team like that. This is only Node 3 so I cant wait to see how my day progresses...

Oh, and what is up with crazy power on AI side? Their Lumi - level 66, gear 7, 6* one-shotted my full health level 70, almost gear 8, 6* Lumi.
