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.
your list has fantastic depth, I will refer to it often to get another point of view.
