Topic says it all. What class do you plan on starting with (if you haven't played in Beta) or what class do you have your heart set on being your main (for those who are extensively involved in Beta)?
For me, I'd say it's a toss up between Hunter and Burglar. I've always loved doing ranged damage, but the whole starting conjunctions thing (kind of like SCs in FFXI) also has my interest perked. However, I haven't really messed with Burglar in Beta, so I have no clue.
