So the thesis of the discussion is now:
High Pilot Skill + positional modifying actions (Decloak, Barrel Roll, Boost) are the central problem with the game's balance, as they completely invalidate the middle Pilot Skills - either it's 9+ or it doesn't matter - especially when combined with multiple Action economy and super defensive tech (Autothrusters, regen).
The supporting arguments are pointed towards three examples: VI Whisper, Soontir Fel, and VI Poe Dameron.
Solid support is the rise of VI Vader just to counter these pilots via superior positioning (as it's the only way TO counter those pilots!) and how VI Han Solo, VI Wedge, and VI Talonbane Cobra fail to have the same effect as they have minimal (or NO) repositioning, no action economy, and/or still fail to ignore Autothrusters.
Counterarguments?
I don´t think that Poe deservers to be in that list. Boost or barrel roll alone are not a tool for evading any incoming fire and getting into firing position at the same time. Boost + Roll might be though.
