I'd like to start by saying that these are just recommended key bindings, they've proved efficient with me, but everything relies on you being comfortable with the champion.

I change all to smart/quickcast except for item 2, then change "quickcast item-2" to shift-w, so that when I want to ward jump, all I need is to have my wards on slot 2, and I'm able to press "Shift+W, W" to have instant ward jumps.

-Before you Q-R-Q combo, it's important to note that you should w twice that way you can spellvamp off of your ult and q's. late game it'll heal you from near death to around half.

-W Gives you spellvamp. Spellvamp is good. Smite is affected by spellvamp.

-Don't try to make flashy plays, just win simply by out trading people

-Flashy plays are cool as ****, do them all the time and throw the game while you try to do them. It's worth if you say it in all chat.

-Everything you build should be based on what you are going against in lane, if you're one of the people actually reading this damn thing instead of looking at it mid game, then you should be fine.

-Kicking their team's tank into your team's adc is a bad idea. don't do that. you're not insec if you're looking up a lee sin guide on mobafire.

-To instantly clear a wave @ lvl 18, use E, auto big creep, rav active. auto before rav to get your energy back from e.
