Seems Like Riot made LP gains lower than they should be with a high win rate.
I remember last season or at least the seasons before that, when I would place on an older account or a brand new account, you'd always get good LP gains after placing until you ended up fucking up your win rate. I go 9-1 typically in my placement matches on my accounts and from that I only gain 26 LP per win, when in the past it would be around 32 LP per win. While retaining a high win rate it continues to stay around the 27.
On an account I was playing flex que on awhile back I was getting the good LP gains and was skipping divisions 4 and 2 usually.
Really curious what they changed with solo que. I preferred being able to shoot up to my main elo rather than spam more games to get there.
