Literally all that would change if our beloved pro players actually bothered to play TG is that #1 would be 2800 instead of 2500 right now, and maybe like 20 more players would appear on that top 100 ladderWe are talking about rating not skill
Rating shows skill only among ppl who play that mode (TG).
Higher players don't play TG on de, so rating increase fast without skill increase.
