the advanced-1 and advanced-2 is a bit puzzling. doesn't look like there was a far and above team in any of the divs outside of invite (maybe could argue for nonagon infinity but looking at the games they had on paper, they were beatable in some cases) to make a case for adv-1 and adv-2.
div sizes seemed fine too so not sure how that argument justifies adv-1 and adv-2 in the article. if your issue is div size relative to skill level there's a better solution than this, because i'd argue that this creates a further skill gap even if main in essence is the new intermediate
btw why are we removing upward for steel. it's now 2 pl, 2 a/d, 3 koth. is there something wrong with borneo that makes people not want to play that map
