Parch has a lot of interesting ideas regarding INN players.

However, in my opinion, the current system of INN players is fine. It is my belief that to implement such a system as has been suggested would require utilizing programming resources to fix a problem that is either non-existent or very small. It also seems that programming resources are already very limited as items which have been high on the priority list take too long to resolve as is.

As far as non-INN prospects taking a valuable roster spot and providing minimal usage I say that is just the price you pay if you want to carry these players. Thats part of the challenge of construcing a competitive roster.
