Do you hit anything at range 4-5 with those 2 extra green dice, is it worth it for u?
Range 4-5
Yep.
Ships with 0-1 agility are still good targets. Other Huge ships, VCX, Decimators, Lambda/Upsilon, Falcons .. even Y-Wings, B-Wings etc.
Being able to shoot something which is too far away to shoot you is also good.
