This is exactly what happened to me. I was too tempted by the AA fire director. 150 buckets later I got it, but I'm not sure it was worth it.

When I was frontlining E-2 on Day 1, The BB Hime cockblocked me from advancing for a few runs.

God this all too true. E-1 lure you to a false sense of security and then E-2 further your confidence as you wrecked everything with ease.
Then come last dance, Symbiotic is there to ram her beast's giant middle finger up your unprotected and overconfident ass as hard as she can when you bend over to try and prepare to pick up your drops.

True. But I didn't get much of a trouble in this one. In fact I manage to complete 3 maps in a single day.

Bringing support shelling might be a necessary just in case. Same goes checking other people's intel.
