[Suicide Junkie]

In a fleet battle, there is more than enough manoeuvering to do. In fact there is probably a little too much dogfighting, considering also that you are supposed to be commanding ships between destroyer and battleship size, not piloting fighters singlehandedly (although that's moddable).

Also consider that this is based on the Space Empires series, where combat has always been 2D.
That may change for SEV, perhaps, but I don't see it adding much value.

Fighters do end up swarming all around captial ships, and I've seen some very amazing screens (Oh, I so wish I'd hit the printscreen button)...
coming around a star, I see 7 fighters hammering a pirate ship from all directions, while three capital ships bombard it with APBs and torpedoes.
