1. Be agressive
2. Try to outfarm your opponent
3. Teleport to lanes whenever needed
4. Make sure your teammates wants to pick a fight before stepping in.
5. Be defensive if you have killed enemies toplaner once or twice because then you will be the enemies focus.
6. If you are being focused try to make the enemy jungler at topside as much as possible, because then it will be easier for your teammates to get turrets, drakes, buffs and alot of free time from ganks.
Whenever you and your team is going into teamfights make sure they know when and how you will use your ult. Not because it matters so much, but if you are playing with fiddlesticks etc. They will take a combo with your ult to make sure not to lose the teamfights.
