Just a few silly questions for you:
1. OPs are for 50s only?
2. what are the dailies and weeklies avalaible to non-50s?
Any heroics on the planets are daily
Spaceship weeklies and dailies
Worldbosses' weeklies (kill all bosses in list)
Flashpoints' dailies (run one of thr flashpoint in list)
the last two you can take from the terminal on the fleet (suply area AFAIR)
PvP dialies and weeklies
also you can try Belsavis dailies from 47 lvl
3. the rakghoul quest series is removed from the game, right?
