So as you can see IÔÇÖve made some categories that champions fall under. I tried to put them into specific ones for the roles they are best at but a lot of champions fall under several categories so if you see a champion in more than one donÔÇÖt worry too much about it
This is going to be an ongoing thing that I am going to work on. I will define it, make it better, make it more clear as I learn more about the game and think about each championÔÇÖs best strengths. I will eventually have it to where the champions are correctly placed at the top if their respected category instead of putting them in tiers right from my list. For instance Pantheon is the #1 melee DPS now but he sits in the top of tier 2. I want to change that so itÔÇÖs clear heÔÇÖs the top of that category. When I have some more time I will redo this and change it.
So with all that being said. I hope this clears up my tier list a bit and makes it easier to understand why champions are placed in each tier.

Tier 2 ÔÇô Shaco
Tier 3 ÔÇô Poppy, Nunu

Oddball Roles: Nidalee - Now she fits into so many roles its extremely hard to place her one. I placed her in support because I feel that kind of suited her best with her map control and heal. I mean she cleans up fights well, she pokes well, she has map control, she can heal quite well, great lane control. SheÔÇÖs just such an oddball role. So any champion I have a hard time placing will go here and I will explain the best I can.
