Starting with level 1 you should ALWAYS try and get a cheese kill with your Q (Chomp), afterwards play safe and only go in if you are sure they can't escape, after you get Essence Reaver you can play far more agro and push, when you get your Hullbreaker you simply perma split-push, if you could not end early and are in late game see how the enemy team responds to your split-pushing, if they don't do much try and end, if they consistently keep you away from ending play with your team and wait for a team fight, if you win you can instantly end the game simply due to your tower melting.
