Just going to 3 would be the easiest for sure, I am happy the way it is because i roll 4 goalies ATM and have worked deals to get ti that way, but I would be ok with 3. i don't like capping the number of games nor like going under 3 active Goalies, either.
I just don't want to change toooo uch to an already great league, but agree that parity is a good and positive thing!
