Information about the upcoming tier list

The "why?"

Ok so it's been a long time since I posed a Tier list, so long in fact that the ARAM map changed twice, and the meta has shifted a considerable amount.  This is but part of the reason why I am creating a new tier list. 

The "how?"

With this new tier list I don't want to make as many "informed" guesses as I did in the last tier list (given I played a lot of aram back then, so the guesses were fairly good in general), instead I want to give as accurate a tier list as I can.

To this end I have been systematically playing or spectating many ARAM games over the last month or so, relearning the meta anew, recording who won and who lost each game, along with who got the kills and how powerful I felt each champion was, which often is influenced by their performance in the game, as well as the graphs after the game showing their damage dealt (to champions) and their healing done (obviously champions with more cc are expected to have less of these stats on average, made up for by how effectively the used their cc in the game). 

And recording these stats I'm giving each champion an average rating dependant on these 3 factors:
How well I felt they performed, What their win/loss ratio was, and how good their Kill/Death/Assist ratio was. 

I then tweak these ratings as I see fit and organize the champions into tiers based on these ratings. 

Lastly I will look over the tier lists and move champions up/down on the list if I feel like the rating this system gave me was not what the champion is capable of, or is much too high for the champion in question.

The "When?"

I've just finished up University, so I should have a little more free time now, but that's not always the case, I might find I'm just as busy now as ever, but any way you look at it, I'm getting a pretty good idea of how powerful most of the champions are, and should have the tier list up within a week if all goes well.  

 Of course feedback is always welcome before and after I get the tier list up.  If you have any questions about the process I'm using or suggestions to get a more accurate tier list, shoot them my way and I'll try to answer them as best I can. 

GL + HF all.

The Math and a more detailed explaination

Ok so I'll post a more detailed explaination of what math I'm using for the tier list and why at the bottom here:
How well I felt they performed (on average) = about 56% of their rating
What their win/loss ratio is (on average) = about 33% of their rating
How good their K/D/A was (on average) = 11% of their rating

How well I felt they did is the most important, because there are so many factors as to how well a champion did that the other two categories don't include, which is merged into this category. And also because this is MY tier list, so how good I think a champion is, is what's important.

Their win loss ratio is given 33% because after all, the end goal in ARAM is to win, so it's rather imporant to rate a champion on how often they actually accomplish this.
Note* To offset the large amount of dodging that happened on the proving grounds when the other team had certain champions (Nidalee and YI for example), I have reduced the importance of winning for these champions, on the grounds that if their opponents didn't dodge, they probably had a pretty good team themselves. It appears that dodging is no longer an issue with the howling abyss, so I'll probably remove this tweak in future versions of the tier list.

This system then gives the champion a ration between 0 and 4, so I made arbitrary break points in which I consider them "higher tier", right now it looks like I'll be using these:
rating 0 - 1: God tier
rating 1 - 1.5: tier 1
rating 1.5 - 2: tier 2
rating 2 - 2.5: tier 3
rating 2.5 - 4: tier 4

Another factor that influences the champion's rating, notably their win/loss rating besides the percentage they won, is how many games I've seen them in. The more games I see a champion in the easier time I have of giving them a higher tier, because I'm more confident that a champion I saw win 5 games in a row is going to win again, then I am a champion who won the only game I saw them in. Here's some comparisons on how I value seeing a champ in more games:
1 win and 0 losses is roughly equivalent to 5 wins and 1 loss, which is roughly equivalent to 8 wins and 2 losses, which is roughly equivalent to 60 wins and 30 losses. 
1 win and 1 loss is roughly equivalent to 3 wins and 4 losses, which is roughly equivalent to 6 wins and 9 losses, which is roughly equivalent to 50 wins and 100 losses.

After I arrange the champions into tiers I will look at notes I took after each game to see if the numbers placed any champion too high or too low on the tier list.
