8 active players regular roster seems a good idea. For the actual state of things, these new permissions such as point 3,4 and 6 are good inputs to involve more players into competitive and having less problems with teams showing up. Point 4 always been "used" before Ark decided to makes his own new rules, and its a real good thing till captains/team are consensual!
About point 5, it would be nice if done in such a way that players gets raffled off to all teams and make something to force teams to let this "free agents" play a minimum of games at least during regular season.
About next Skyleague, if we are going to do it after summer i'll for sure make a team, but in late august/early september i won't be able to follow it.
I think if Skyleague gets postponed it would be good to make some short tourney during august, to restart bringing interest to competitive from some old players and get involved and better prepared the rookies.
