My COMPLETE TIER LIST. Ive played dom far more than most players. Still evolving though.
T1 Irelia, Akali, Heimer, Rammus, Jax, Poppy, Xin, Kog Maw
T2 Singed, Teemo, Yorick, GP, Swain, Noc, Panth, Talon, Rumble, Yi, Tryn, Garen, Morgana, Shaco, Malz, Sion, Alistair, Kat, Sona, LeBlanc, Shyvanna,
T3 Veigar, Nasus, Twitch, Eve, Annie, Ashe, Blitz, Brand, Caitlyn, Cho Gath, Riven, Fiddles, Graves, Janna, Jarvan, Kayle, Karthus, Xerath, Renekton, Sivir, Soraka, Tryn, TF, Udyr, Urgot, WW, Mao, Ezreal, Kassadin, Amumu, Leona, Mord, Shen
T4 Orianna, Wukong, Cassiopeia, Corki, Mundo, Lux, Nunu, Nidalee, Skarner, Ryze, Tristana, Vayne, Zilean, Anivia, Kennen, Malph,
T5 Galio, Gragas, Karma, Trundle, Taric, Vlad,
Criteria by which I rated champs;
T1-- If they have one of these champs you have high potential to have a real problem.
T2-- Great champs, no doubt, can easily dominate the game.
T3-- Can be good, really depends on player, but about average for the most part.
T4-- Just not that great in dom, In the hands of a good player they can pull their weight, but thats it.
T5-- Just plain weak in dom.
This one is mine, I have 2.5 k wins total, though maybe 300 in dom.
