The main problem is the mindset of the playerbase, nobody is going to invite a THF to DD over a WAR, MNK, DRK, DRG or SAM unless they're a good friend or placebohunter is needed, it doesn't matter how good you are.

Look how many threads there are of thieves saying they've out parsed real DD`s on THF, the response is always the same, "if you out parsed a DRK on THF then that DRK sucked" it's never, wow you're a good THF that knows how to DD, it's always the other DD`s suck.

This mindset is what is keeping THF out of Adoulin events more than the job itself. A lot of thieves just play the job for TH because they don't see a reason to be the very best THF on the server because it still won't get you into events.
