As in:
Credit caps, having to pay in coins to unlock race options for new characters if you didn't finish a class story with whatever race it was, paying to unlock hiding your helmet, paying to match colors to chest, paying to get access to a crew skill slot, paying for action bars, paying for weekly access to instances/PvP, etc., not getting some rewards like lockboxes n' such.
I probably bought a few unlocks for those as preferred so it's a moot point if it's still around but is there anything that's still annoying to deal with unless subbed?
