User blog comment:C4bal/(Most?) Viable Champs for every position!/@comment-7481207-20140309131328

There is this tier list that is up to date with the most recent patch:

As for those you have on your example list, all of them are at least on tier 2 (basically viable but not super strong) and a majority of them are higher than that.
