the potential of pairing a 10k with 150k player is questionable, imo rank range should be smaller and min. rank be 100k or make max 20k or something. the balance of ranks is way to much. the gap should be smaller, tbh it'd prob be better as like 30k - 120k. rank doesnt really mean much in terms of skill but a 10k player is 10x better than a 100k+ player in every aspect and theres no arguing that. it'll come down to maps being too easy for the highest rank or maps being too hard for the lowest rank with this kind of range, there's no good balance.
Update: Currently have 40 teams already. Looks like Group Stages are tentatively going to begin on the weekends of March 10-11th, and March 17-18thth, and then Bracket Play after group stages will be on March 24th-25th in which every match will be streamed on twitch !! If you have any friends that are between 10k-150k make sure you tell them to sign up!!!
