We had Priest, Rogue, and Crusader on the roster; pretty much poster boys for Trillings. I'd have been very surprised if any other race (other than cosmetic hoarder runs) was represented this round. Also keep in mind that I nabbed hoarder on both my runs, so my race wasn't a big deal.
The biggest issue is that for someone who wants to keep their options open for the hoarder badge, Halfling, Gnome, and Goblin make a lot of sense. They lose nothing by leaving their conversions till the last minute, and thus you can make your decision at the very end as to whether you can actually attain that badge or not. This is in contrast to humans, elves, dwarves, and especially orcs that need to make that call right away or else lose out on their primary racial benefit. So halflings have a pretty big meta-game advantage here, and I'd be hesitant to jump on them.
