One fix for tier 2 and get more teams involved and increase the incentive for the teams participating can be, end of stage 2 challengers for all regions the top 3 teams from all regions have a tournament to get 2 spots in champs hence increasing the no of teams to 18 and this gives them added benefits based on their performance in champs towards ascension and promotion to tier 1. M80 like situation can also be avoided by having hard bound rules about which teams can be approached in the middle of the season, example all the academy teams should be the first teams to be approached as they cannot ascend and having academy players suceed would increase the reputation of the respective orgs they graduate from.
