Higher PS arc dodgers? Aggressors hate Soontir Fel, Turr Phennir, Whisper and to a lesser extent Jake, Tycho and Echo.

Sadly thats only half the truth, if you block those low hp ships a mangler cannon with reroll will very likely kill them. But in that matchup it's usually the better player that wins. It is still dificult to arc dodge IGs even with higher PS, make no mistake about that!

Two defenders with flechette cannons and a Firespray with rec specialist, you k turn behind one and stay there piling on stress as you stay behind and the AT Arnt much use against ships that can white k turn and shoot from a rear arc.
