In your opinion, 3E is dead? Really?
System mastery is such a weird concept. On the one hand, I want the fact that I know the rules pretty well to have some bearing on my enjoyment of the game (including in creating characters). On the other hand, I don't want someone new to the game -- or just a more casual player -- to get screwed.
Then you've got the idea of deliberately built in rules mastery, where the "traps" are pretty obvious to folks that are paying attention. On the other hand, if designers try to eliminate that, they create a situation where it actually takes more skill to recognize which options are less powerful, because the gap is smaller and less obvious.
