I don't think it is really a big deal. Past a certain point, you can't fail an aid-another check anyways. Might be significant at lower lvs, but this really depends on the party makeup. If they consist of PCs who are each allocated a list of skills to max out (and the rest dump accordingly), then it may be useful.![]()
Personally - I think that this is a fatal flaw to Aid Another. I don't like the fact that it has a static DC.
I believe that Aid Another should use the Easy DC from page 42 (pre-errata). This makes it a DC of 10 at 1st-3rd, and about equally challenging at higher levels.
