I think flotillas + jamming fields will make their money escorting slow B-wings into battle.

Crap, had my hopes up until I read the next two responses. I suppose it would have been too powerful if it made them obstructed for engagement

Didn't we get a response from FFG on the Station? It does obstruct attacks but does not break engagement or something?
