"Wait, that didn't work right" - the Dysfunctional Rules Collection

[willpell]

Why hello there Dodge and Mobility. Care to explain why you're blocking my way to every melee PrC ever rather than sitting in the corner like I told you to?

more accurately, Dodge and mobility, why are you standing in my way to getting Shot on the Run and Spring Attack

I think of this as a good excuse to take feats that you otherwise would ignore, because they eventually lead to good abilities (or at least interestingly unique ones). Nothing in the game ought to be "useless", but I'm fine with "use-impaired". As long as there's some reason you might want what comes next, forcing you to take something you'd otherwise have ignored strikes me as good use of design resources.
