A considerable number of people find the charge of the Antigua line guns to be rather lackluster. What I propose is being able to strafe (still looking in the same direction when you released the charge, mind you) while firing the clip of the charge attack, THEN stopping to fire off the birdy bird.
Some slight mobility may offer gunners more opportunities to seize use of the Antigua line's charge shot, as not only is mobility a gunner's best tool, the Blitz needle takes the cake for 'overpowered charge attack' to warrant being rooted in place and vulnerable for the duration.
on the idea that the charge needs to be changed. although i always wanted the charge to do just the eagle, not the 6 shots before. that way you still get the best part of the charge, and add speed to it.
