Some people have been talking about various problems which seem to be titan feeding and frigates. Mostly, I think, for multiplayer matches. Dont engage the titan early, dont build many frigates, they are a snack and level up the titan, use pirates to level your titan, etc...
Would change the experience a titan - and only a titan - receives help with this? For instance, decreasing the experience from killing frigates (and maybe strikecraft, who knows), slightly nudging up cruiser experience, and bumping up capital ship and starbase kills? Maybe this would help with the perceived undesirability of frigates?
I am assuming the experience is totalled and divided among experience receiving ships, so just total experience per category, dividing the categories per ship, and then applying modifiers seems like a reasonable code change without a performance penalty - maybe add a couple of O(n squared) operations if I remember my definitions correctly.
