Who would be better to main Riven or Draven? I've seen people hard carry with both but which is more rewarding? ex. which have an easier time with counter picks and which would be better for solo carrying. Yes, I know it depends on the player and the game but I'm asking so i can start maining them in normal and then moving on to ranked 
or 
? (Do I put this in misc or help and support?)
You want to solo carry then you list an ADC?
If you don't want a support, go with Riven.
If you want a support, go with Draven.
My vote goes to riven, assuming you want to solo carry. As adc you're dealing consistent damage while keeping yourself safe, and that would rely on a functional team to help you with, so I'd say riven is more team-independent than draven is.
is the best champion in the game
But I like playing
Draven is the better to main. He's less heavily meta dependant and he lacks a design that will be nerfed as soon as pro's use him. I.e., Draven will be more consistent.
Koalas spook me (NA) submitted about 7 hours ago
Did you know, Koala's often have chlamydia ? That would spook me, but alas, the drop bears, crocodiles, platypuses, Paulin Hanson, snakes, bunyips, sharks and spiders that are trying to kill me all take priority.
The obvious answer here is Ezreal :)
