As I read thru this thread it reminded me of so many threads over at FOE. Many similar suggestions were made over the time I was there, that were supported by the majority of the active players at that time, and were hashed out between those players in an effort to present a comprehensive suggestion. All in all those suggestions were ignored.
That brings me to the reason for this post. It was the consensus of those usually involved in those presentations, that INNO was not going to implement ANYTHING into one of their games, that wouldn't drastically increase their revenue stream. In their opinion they provided a working model, the revenue they were currently receiving proved that, so they follow the "If it isn't broken, don't fix it" mindset.
None of this is a fact, just speculation among many, many long term INNO game players. Just thought it was worth mentioning.
