This tier list... No.
I once disagreed with Sam on his tier list back when I was #1 spot. But since have learned Sam knows his **** and it isn't a good idea to make your own tier list regardless of your experience. Because not only will your tier list be trolled, but if it is anything other than Sam's tier list, it is wrong.

P.S: Sam Shyvana is god tier. (And she has a slow hue)

This tier list is way off on the aps.

Don't care for a lot of placings on this list.

Specifically, Akali, Cho, Nid, and Nunu are all too high. Olaf and WW could probably be higher, as well as Grag.

Riven is not high enough. I'd take Riven over GP, Yorick, or Jax in *almost* any matchup. Better mobility, more CC, stronger early game and more well-rounded power level as the game progresses. Riven is strong all game long. Between Riven's mobility, cc, and exceptionally strong early game (as well as the rest of her game being very well rounded), I see her as pick or ban in many situations.

AD nid is strong, & your problem with Nunu is (I assume) that you probably don't see good Nunu's very often. The champ is strong for 3's; most people are just not good with him in 3's.

One of the ones that stood out to me, as worthless as my opinion is, was Kass. At 6, I feel like he is extremely dangerous in 3s, because he can dodge all over the map. I thought he should be at least Tier 2.
