I recommend not using your Defile (E) against minions, unless you're in a hurry to save a tower. If you stick to lay waste and autoattacks for lasthitting, but still level E, you get mana back for each minion kill so you won't run out like ever if you do it right.

Your E is for fighting players imo, but it will drain your mana fast, so be prepared to go home after any serious fight.

Also you shouldn't primarily aim for picking up kills with R imo, it's better to feed your teammates by ulting during dpsraces so they win. Of course, you should still pick up a kill here and there, but don't have it as your primary goal, and try to minimize killstealing. You still get gold for assists, so you will get a little fed whatever happens really, it's more important to feed your teammates since in a long game you'll probably max out on items first anyway.
