As @NyoomVoyager points out, bottom picture was built by Echo on one of my rounds. Echo was 2 CTs + an FTL and FOB was built by an MT in a power loader. All 4 squads inc Bravo was in A-Block and eventually fell back to hold the very built transformer.
As I note here: Lessons from FOB Rework (1): STOP putting Bravo on FOB!
Bravo would lose its identity as the Defense Squad but they definitely have no reason to be on transformer. Death Turrets being removed on FOB Rework wouldn’t change that as the Death-Rockets can easily destroy any attempts to steal the MT off LZ.
During my rounds on FOB Rework, after Carrier was prevented from destroying the transformer, there were 0 takedown attempts as no T3 wanted to walk there.
TLDR: Death Turrets + FOB Rework will push Bravo off of FOB. Maybe that’s a good thing. But no Death Turrets changes nothing to FOB Rework.
I think @Itus is definitely right about lowpop, Bravo is normally 4 guys and there’s no pilot and often some IO or ASO in CIC. Maybe the Death Turrets should be a handhold that scales with pop?
