It's even simpeler..
If a player creates a character he loves, but is not optimal, you as a DM should take this in note and not throw hard monsters to hit in a encounter...
If you have a mixed party with optimal and sub-obtimal characters, just throw in a mix of enemies..
I just thought of something
Is it possible ... just possible that wotc thought that BOTH
1. We had maybe one too many feats at paragon, and epic.
2. We had too low to hit in the respective tiers.
Thus they killed two birds with one stone?
What I'm saying is, it would be very hard to argue that traditional feats make characters so powerful that they need to be limited.
