Have about 35% winrate now. I play pos 2,3,4. have my bad games but mostly outperform everyone on the map. I've been consistently losing mmr and the gameplay at this level is just so frustrating. If I play core, I win my lane most of the time. I gank safe lane or hard lane depending on how the game goes. but the enemy team bounces back anyway. Then there is a point when all my momentum is gone and its all down to team fights.

If I play support, same thing . I win the lane. rotate mid/off if need be. make sure my carry has vision. go as far as plugging the enemy's team jungle. but thier hc still bounces back. I communicate, adjust item builds based on the matchup and set game plan based on the drafts. I still lost 9 out of the last 10 games....
