It seems like the expiration date is keeping a lot of players from rolling these seasonal races.

As silly as I think this is (don't get me started on "perception is reality"), it has had the unintended effect of giving me the rarity of race that I hoped for. I almost don't want to correct this thinking.

Also most people when they roll a character want to think it's going to be a game changer that age dies, and an expiration date kills that dream and so they don't bother.

It has already been mentioned that we have the ability to modify the end date of a character should they prove particularly influential.

Also Centaurs look cool, but the Vuln_Climb, Vuln_Crawl, Vuln_Boat is really rough.

Having put in most of the flags that check for climbing ropes/ladders, there is not a great deal that VULN_CLIMB impacts; and the only characters that have no navigation around that limitation are Battleragers. If it actually became a game-changer, I would initiate the implementation of a way to haul Centaurs up or down such exits (though I wouldn't expect a Gnome with a rope harness to be enough).

I have played characters that have never once used the CRAWL command, so I'm having a hard time seeing the issue there.

There is actually an expansion to the VULN_BOAT limitation that I would like to see take place, so I'll wait before I comment on that.
