Note - I did not read the entire thread. Looking down on 'lesser', 'scrub', average players or those not playing multibillion incarnate builds is troubling.
@aethereal please don't speak for me.
I use some T9s mentioned as intended. Could some of them use a tweak, sure. @Vanden @MetaVileTerror @Haijinx and others had some interesting suggestions.
In my opinion - It is great that we can build out of the need for 'god-mode' powers. Intentional or accidental, this is part of the game, learning a character and adds to replay-ability.
The mentions of overhauls or replacements would seem to benefit power gaming disproportionately at the cost of others. This should be heavily taken into consideration.
Cottage Rule summary for those curious:
An existing power will not have its core functionality and purpose changed, though its strength may be altered and effects secondary to the power's true purpose may be added or removed.
