This does very little to enhance your "goal" of diversification as end reducts is an enhancement usefull in most every power. This limits why I would want to use them.
If you REALLY want to throw us a bone that might shut down some of the critics then look at changing your your formula. Right now its roughly based on 6-slotting of training enhancements. So my third SO is allready losing effectiveness. Make it based on 4 SOs and you start losing (and you'll get tons less flack on this).
