However, not all characters are affected by this math/design error or the character may be happier with another feat. As I showed above, the 20 dex cunning sneak dagger rogue doesn't need more bonuses to hit as he's above the curve as/is. Why force him to be even higher above the norm when he might want something a little more exciting than a plain old +1 to hit?
Who doesn't want to hit on a 2? Seriously though, I don't feel like I'm taking anything away from people. Before the proposal, at level 5 you got a +1 to hit. If #10 passes, then after the proposal, at level 5 you will get a +1 to hit with the majority of your attacks.
However you are voting on just that; you're just debating on what feats qualify for the free slot. I'd rather have the option to not take an expertise feat if I wish. I have better things to spend it on than a +1 to hit and it's not like that +1 would matter THAT much the way IC rolls. As someone noted above, nn extra +1 when you roll a 1 or 2 on your D20 doesn't help much.
Yes. I can't deny that I am voting to give people a feat. I'd rather not. I'd rather have #4 win, with some modifications. I liked the old house rule, but I see that it's going to cause problems down the line. So I voted for the choice that a) is most like what we have right now, and b) has a chance of passing.
I don't vote for third parties in politics either

By the way, personal experiences mean very little to me with regards to probability. For example, I know of at least three times when Haruka has missed an attack by exactly 1, and two of those were with encounter powers (yes, I finally missed with Vampiric Embrace. Hurray for Sacrifice to Caiphon). So if I were using that as my only sample, I would say that a +1 to hit would in fact be extremely useful. However, I still believe that IC is random, and that some people are rather unlucky. If you believe IC is out to get you, why not use a different roller?
May I ask what you see as the downside of letting the slot be unlimited? IMO I can't see anything lost by it and we'll gain a bit more diversity if some people don't pick an expertise. I can't be the only one that'd pick a non-expertise feat.
The downside is that it doesn't solve the problem as I see it. By the time you hit level 5, you've already chosen a few feats. Expertise isn't going to ruin diversity at that point. That being said, I wouldn't take Expertise at level 5. If given a choice, I wouldn't take it until it jumps to a +2 to hit, even though my "empirical evidence" shows that +1 to hit would be super good. I'd rather have a familiar, or Bravo, or the d8 curse feat.
But the problem, in my view, isn't that characters don't get enough feats. It's the attacks not properly scaling with defenses issue. I think #10 solves it better than #6. I think #6 also solves the issue, don't get me wrong. I just like #10 more. As a judge. As a player, I'd prefer the restriction-less feat.
Argh, I feel like I'm splitting hairs for no reason. They both solve the problem, what does it matter.
Yes to #6. And #10. Now #6 is winning. Yay #6.
