Yoo guys, I've been losing a LOT of games since I climbed up to emerald 3 and one of my major struggles are pantheon sup and ranges like senna and ezreal (adc)/caitlyn (adc), what can I do/pick against these matchups? And i've been noticing that the majority of my losses are because I played really bad on lane phase and my adc got diffed because I couldnt keep up the pressure
Any tips are very much appreciated
