I watched sir gorgeous guide, then smashed my head against a brick wall for 8 hrs. That guide is bad.
It's just Ian's is pretty good in principle, but he had insanely good luck on the run that he won.
That's no Moon's vid I found much more helpful.
It's not speed wins in this one. You want some things to happen before you topple gas, like echo grenade asap, rex form up. Don't use aoe unless there is benefit to it. Crit avoidance arrows on droideka and magna help a lot to get the rng on your side.
