Surely I can't be the only one seeing the same champions over and over in ARURF

I have yet to see a Kog, Poppy or Lee.

I've played like 40 games, and I've seen 2 kogs, 1 wukong, I think 2 eves, 1 poppy, and 0 lee sins.

Your not... its called people abusing the fact that you can hop on a smurf that has like no champions buy a few goood urf champions and usually get one of the op options because all you have are a few op urf choices and a reroll every game.
