Against turrets, sure, but against an arced ship Range 3 is the only trigger. Fine by the Aggressor, which is quite happy firing its Heavy Laser Cannon from Range 3, but the elite TIE interceptor wants to be close up so it can use its arc dodging capability to the maximum.
I actually sort of think this is where FFG goofed with AT.
The 'out of arc' requirement is fine and all, but for the in-arc range question...any Interceptor worth anything is going to want to CLOSE range. Either because it's a "cheap" generic, trying to set up blocking collisions...or it's a high-skilled Interceptor that wants to take advantage of the smaller arcs at closer ranges to arc-dodge.
And AT should actually have reflect that latter point, anyway - a ship jumping around unpredictably is going to be more of a problem at close range vs long range.
Would have made a lot more sense for the in-arc bonus to be associated with 'range 1' vs 'range 3'.
