Uh, I suck so I can't exactly play with you on duo queue or else I'll either be rekt or you'll stomp (most likely both, but too a smaller degree), but I'd like help...
I mainly play Diana, but I'm very indecisive right now cuz I'm saving up for a name change (at ~9000 IP! 4500 to go!), so I'll probably get Kha after, since I played him on normals for about my last 10 games, and I did pretty well and it was fun (though I did not know you could Q in mid-air. Or hydra.)
And there's really nothing that I don't need help with, though especially my habit of not doing something that I should just because I can get away with it (e.g., not warding from a place they can't see me.)
