Agreed, I'm leveling far too quickly, I'm a Commander and haven't finished more than 1/4 of the Lt and LtCmd missions. I haven't had to do a single patrol or exploration. I'm going up a rank every single time I play the mirror fed mission - I've ranked up 3 times in an hour from that before + another 3 ranks just from DOFF stuff.
I don't know if ranking is accelerated for Tribble so we can try stuff, but if not then this is seriously bad for the game.
It's extremely accelerated on the Tribble Server for the purposes of getting people to push on through and get the higher level stuff tested as well.
