pro-rel is an option to implement in a few years but RIGHT NOW orgs need a strong financial sense of stability. Look at the A-League (Australias footballl top flight). We started off as a franchised league, pretty simmilar to VCT, but now we're starting plans to implement PRO-REL into these leagues.
But in order to do this we needed to wait for:
T2 clubs to be financially stable
T1 Viewership to be a majjor incentive
T1 orgs income to be both a major incentive and stable
T2 clubs to even want to go into the first division with their smaller stadiums(viewership)
Imma post what my opinion on the best possible VCT option is in forums
