Well I always play a thief and usually pick the race best suited, but I am having the Mithra race issues (dunno why, I have played Female Chars before and I am comfy with my sexual orientation...maybe it's because I am forced to do so).
If I knew what the caps were and that Humes were able to reach the same point of diminishing returns as Mithra, I'd be set.
You're going to be staring at this character every time you play, with all your jobs. You might not even end up a thief.
The most important thing is that you make the character itself something you like. Really doesn't matter if you have 10 more dex or whatever, if a month later you really wish you were a hume.
Exactly Anya. I picked Elvaan cuz they appealed to me and I was *planning* on going WAR until I got PAL/WAR. But now that has changed to DRK/THF. But like these people have said, pick the race you like first off. If you are completely in love with a job, and want to be the absolute best there is at it, then race can be considered, but I don't think the difference in the race stats are significant enough to stop you from using a certain race/job combination.
