The slef concealment stacks with itself, it just doesn't stack with the Improved Invisibility.
Exactly, what good come of taking concealment if you're just going to turn around and take invisibility. It almost makes concealment a useless feat to take as a req. However by itself, you only need to take 5 times and you get total concealment all day long.
Take for instance dodge/mobility/spring attack
Each logically makes sense to take in that order. You must be able to dodge someone in order to move in to their threat ranges more effectively, and you must be able to move into a threat range effectively before you can do it without provoking an attack of opportunity. However, each can still be used with or without the other.
If you wanted to close in on a wizard, and not back away after your moving in, then mobility would still be useful. The feats therefore are logical, but still seperate of one another.
Concealment seems to be more of a different path than my invisibility. While Nat inv is based off of what you eat and how well you can manage your body, concealment seems to be more of how well can you hide yourself in broad daylight.
Just my opinion, its not like I took it out of a book or something.
