Just keep your accuracy going as much as possible.

You are using a two handed weapon, you miss one hit and thats a lot of TP you potentially lost. At the early levels all 2-handed weapon jobs (DRK, SAM, DRG, sometimes WAR) miss a lot because the gear just isnt available, but once you hit the 30s you should start seeing accuracy gear. Get it.

DRGs are made fun of a lot, a lot of the time its just a bit of humour and no DRG I know has any more problems getting parties then I do as a DRK.

Plus, Polearms look cool as hell.
