Aparently winrate should influence Division
"First, adding Iron and Grandmaster tiers introduced a bug that allowed a nontrivial number of players—up to 155 on one server—to get to Grandmaster despite having a win rate below 40%. Another related bug allowed some Diamond players to climb to higher ranks than they should’ve been able to." Why should win rate be involved? How does it relates to rank games?, shouldn't a rank game be balanced, not influenced by (Riot). "climb to higher ranks than they SHOULD'VE BEEN ABLE TO". Riot knows everything apparently. they know what you will eat tomorrow.
