Hi,

 

I recently came back to ToR and startet doing Galactic Starfighter.

So far I am enjoying it.

But my question is: Does it have any impact or synergy with the rest of the game? (like getting character-exp, or cosmetics, or epic equipment, or commendations, or lageacyunlocks, or new quests, or credits etc.p.p.) or is it just purely a minigame?

Your character gets XP and credits (like in a normal warzone). The only other gain, Requisition, is related to and useful for GSF only.
