I played against three BTL Y wings with ICTs and one bomb armed Y wing (all scum ships at PS2) and tore them apart with five scyk interceptors (four cartel spacers , one stock the others had either a mangler, ion, or heavey laser cannon on and they were led by serissu)
So i mean my scyk list isnt strong, its just fun but the Y wing list struggled against it.
I dont think a 4 BTL with ICTs locked forwardss is a great allrounder as they just couldnt land a hit on evading scyks with serissue in close formation.
