In the start at game with carry's its best and be with the ranged minions and kill the melee minions if they come to you. As carry its normally in level 8-12 you not carry more and have some items, then you can begin to play more offensive.

Is allways in midgame the teamfights will begin or ganking. play safe in teamfights and killsteal if you can, if the team be angry over killsteals and say sorry/sry or say ''sry i didnt see you use ultimate and ignite

In lategame are carry's best if you have finish the build you can make tons of damage with physical attack damage.
