Tier List 18/05/12 - ChrissyDoc
Tier 1 = These champions are a fantastic pick for their position, they will usually dominate their lane unless they have been counter picked, and are a great addition to any team
Tier 2 = These are still good picks, they are very strong and can do well if your team works well together, however they can be hard countered, or it is possible to lose your lane if your team doesn't work well. If you are great at playing a champion from this tier, it is a good as a tier 1 pick.
Tier 3 = These picks are ok, but the other tiers generally have better picks and you could do a lot better with them unless you happen to be very good with a specific champion.
Tier 4 = I wouldn't recommend Picking these champions because there are much better choices, the only time I would recommend picking a champion from this tier is if you happen to be a great player of that champion, because if you can play one of these champions well, it is better than a tier 1 pick if you can't play them well.

Again, this is just my opinion, if you think otherwise, leave a comment, maybe you can change my mind. I will handle all comments nicely, even if you are being aggressive. If I have missed a Champion out or made a mistake, please let me know. Thanks for reading.
