Play an assasins or burst mages. That is if you get mid or jg. If not try playing an initiator bike Zac, amumu, and malphite then your team should converge onto her. Rengar easily jumps her and oneshots her. So she condemned you away, use a bush and even then sometimes, they can't even react. My last game as rengar, their ezreal would die in half a second and I don't play alot of rengar. Ezreal also has a blink I might add. Talon, easily oneshot people early over and over. Q ult e dead. Fighters and tanks may have issues because of kitting. That's why melee champions don't work well in lol but because dota has turn time, meele heroes are being played as safelane and that's the equivalent of adc. For instance, phantom assassin is the vayne equivalent in terms of damage because of her ult which is a crit passve without an active (up to 500% damage on pseudo random) and she's melee. Some divers like vi could probably kill her in fights. Vi has 2 dashes and usually builds bruiser and has a simular 3 hit w passive ability. The only difference is its physical. Let's put it this way. Vayne is a way guy with a gun and vi is a monster in size with a light Kevlar vest and a weak weapon. Tanks have heavy level vests and no weapons.
