I just read this entire thread and I didn't see any posting for Auto Insanity teams (non-Gunner only.)
Bruce Eddie's marks can be an issue, he's the new meta changer in Arena, so I hear. I'm only grinding insanity for the Artifacts.... I need 1 more.
I already have a set, but hey.... you never know when you will need a second.
I used my arena def team w/ an alternate 4th.
100% win on Auto
Best time 2:07
Avg. 3 mins.
Alex Ed- Ragnarok/cosmic with Dominance
Moonchild- Labyrinth/cosmic
Lilith Nightmoon- Serenity/Grail/cosmic
Maj. Malakhov-Singularity
Even if Bruce & co. kill them off, Alex w/ Rag & Dominance is always the winner. Besides Malakhov, it's really a "no silver" team, plus Lilith & Malakhov always revive.
I might try A. WW or something.
My attitude is kinda "meh."
