I think the assumption is that you could be irrationally attached to your own pet ideas. Which may be true, but if it's a REALLY bad idea the other judges will overrule you.
And on the flip side, it's useful to have a vote in the times when you are able to see your own proposal in a balanced way. It would suck to propose something on a whim to see from the discussion if it's a good idea or not, become convinced it was a bad idea, and then watch it pass narrowly because you can't vote against it!
Speaking of proposing something on a whim, I was just thinking about Sacrifice to Caiphon and Reaper's Touch. If a non-warlock wants to be able to sacrifice to Caiphon to get powers back, they can just multiclass into Warlock to do it. You pay an extra feat, so the warlock is still better at this, but it's possible.
However, if a non-Shadar-Kai wanted to take a Shadar-Kai only feat (yeah, yeah, as printed Reaper's Touch isn't limited, but there are lots of others that are), then they have no recourse. So I was thinking, why not add a Bloodline feat (described in Dragon 371 and Dragon 374) for each race, which qualifies you as a member of that race for the purpose of feat and paragon path qualifications? (Feats and path abilities that build on racial abilities you don't have would be useless, of course, so this wouldn't be useful in all situations.)
Note that the two published bloodline feats (for Deva and Vampire) DON'T allow you to count as that race for prerequisites. Vampiric Heritage says, "You are considered a vampire for the purpose of effects that relate to vampires." (Not that there are any feats other than Vampire Bloodline feats that have "vampire" as a prereq...) Deva Heritage just gives you access to other feats from the Ecology of the Deva article, all of which have the prereq, "Deva or Deva Bloodline". So this is definitely not the intent of the official bloodline feats, but it seems to make sense to me.
