Why do people care about feat taxes?

[Willie the Duck]

Do we really have to do the Dragon Disciple thing again? It's been over a decade, let it go and make a ruling at your own table(s).

What I'm fascinated by is the idea that it proves anything else beyond whether the designers thought through the wording implications of a specific prestige class.

Here is a challenge take a character plot put what it takes to get a Prestige glass.

Play that character from 1st level take all requirement feats and skills to get that class. You will find out why they are supposed to be rare to run across.

I think we're on the same page -- feat taxes are worth caring about (even if you can get rid of them later) because you have to live with them until you can get rid of them.
