Unskippable cutscenes, period. There is very little as annoying as unskippable cuscenes EACH TIME YOU START A NEW CAMPAIGN/STORY MODE. *glares at Freelancer*.
Other than that, though... I'm pretty OK with most game mechanics used: they were put in the game for a reason (or lack-thereof), but if it is annoying, it's probably due to poor integration or insufficient beta-testing.
