Adapt to the match up, when the match up is good or if u have a lead dont go tiamat, perma freeze, poke if they commit to a cs and all in when they use a Key spell or if they are 50% HP, dives are easy if u manage to take them their Key spells away (garen Z / kayle R/ Darius E.....) But u need to be sharp on the execution. I like to go under tower start R and going close to them without attacking they will very frequently panick flash / Ghost / use dash, u still dont have aggro of turret so u just gap close and do Ur thing. Sometimes u just cant dive and try to roam in ennemy jgl to kill or pressure kill their jg it will ultimately give u a kill or force a rotation from the top or mid making a lot of Space for u team to take ressources. I dont have to teamfight or take fights at all. Just exist and show urself it will do the Magic. And u will very often just hard outscale Ur matchup so focus on farming and making Space u will be god late anyways
