I can relate. I'm back playing Seasons, tired of being smashed in UT.
My record is 33-2-2 Div4 now. Playing sometimes with Div7 players.
Most of the time I'm playing against better divisions. Maybe not enough players? Maybe enabling cross-play will help?
Seasons you can see how matchmaking works. Seeing the record of the players you just played, also their previous scores, made me realize how bad the matchmaking is.
UT should have the same system where you can see the history of who you played against. But UT is their money maker, that would expose how they manipulate the matchmaking to make players spend real money in the store.
