Battlegrounds for Dom and TT...
I mean.. Dominate Gaming kept a Dom torunament going for years. Riot could do the same... Sugestion: Solo queue (kind of ranked) you get points for yourself only, based on wins only of course. Max 2 or 3 matches elegible per weekend, or even more if people want. At the end of the the league you give prizes. It could go for months. Like every 6 months the league ends. Etc. You could replace the draft queue for this league on weekends
