Play Rebel's Bluff (Multi mission made by Cetanu) and tell me fighters are unimportant to capship battles.
He put together an excellent mission that honestly, I haven't seen duplicated (scale/coordination required/sheer scope) anywhere 'cept ST:R and BP (*Still playing through all the user made content).
BP has a couple missions which beat it hands down, AA has /one/ mission where it's verging on your comment.
(*I r open to list of suggestions for others).
But seriously, fleet combat includes ships from all ranges, and if you think you'd be useless in big ship battles you really haven't paid enough attention to the coops we've flown together.
We (and, by We, I mean myself and anyone like The_E who coordinates really well with the rest of the wing that you've seen in action) absolutely dominate the course of events throughout the battle, and that's REQUIRED in Cetanu's missions, because he designed those missions with people like us in mind.
It doesn't matter if there's 2 dozen fighters between you and your objective, and they're unimportant to your objective, your objective needs to be completed for the mission to succeed otherwise your capship goes bye bye, that objective is regularly beams/bombers/other tactical objectives.
Strategy is not something devised by pilots, nor should they be able to instigate strategy, tactics, are pilots turf, strategy can react to tactical advantage, disadvantage or stalemate, but it is the admiral/command/etc's responsibility, not the pilots.
