Obviously, start with a midas
Mute your team, because they neither understand your hero, nor the game
Choose your mantra: A) Haste makes waste; B) Soon ripe, soon rotten; C) Rome wasn't built in a day
Hit a strong timing at 17:50: some damage and attack speed is all you need. Time for our first interaction with other heroes (don't sweat if they walk away, your time will come...)
You carried your team so far, now it's time to show the enemy who's boss
It's fine to re-assess your item choices. Of course you didn't make a mistake, but a new situation calls for new solutions
Make sure to jungle between fights, to keep up your farm
Your time is valuable, don't even waste a second
I ban WK every game because he's boring to play with or against.
His play style is just : right click enemies, get crits, stun occasionally, die, revive, repeat
