My experience on this subject is that the most fun is had in a fight if we RP within boundaries we have set up OOC.
For instance. Most events are arranged so that both sides have an equal chance of winning, this provides fun, and the roleplay provides context to it.
We roleplay here to give greater depth to the otherwise endless pvp drudgery.
Sure, it may be very good roleplay for one side to bring overwhealming forces to a fight. However, this doesn't have any respect for your opponent's gameplay.
I will try to balance out fights, often by sitting out myself and roleplaying recording the fight for training purposes (as I did yesterday against the lane hackers while on my LN character, until I got fired on at least...) or roleplaying some fault with my ship.
Now that is both within roleplay and also respecting the gameplay of other people. It's also sportmanship, something which I feel is an important part of any game. It takes out any animosity we may start to feel against those who fly as the opposing faction.
Personally, the most funs I have had in this game has either been completely removed from combat, roleplaying with people, or in balanced fights, be they unplanned or on the fly.
Have your fun, but ensure that other people are having their fun as well. Find some roleplay reason for people sitting out. A damned good one is waste of resources.
