But Cana only has hype, she has always just had hype. No way in the world should she be that high on the list given her feats. If we are going to take into consideration hype then we have to do it for all characters. We can judge were everyones training has taken them base of of the Tartarous arc. Their training parallels what happened to them in the Tartarous arc. Gray during that Arc got DeS magic and that is what he trained with for a year. Wendy got Dragon force and now that is where her progression lye. Lucy got something similar to Stardress a year ago and now look. Natsu now is suppose to parallel Igneel now.

From What Cana showed during the Tartarous arc her progression would be no where near Mirajane's or Erza. Even given her magic it is no where near as powerful as Mirajane or Erza's magic. From what we have seen from her card magic it fails in comparison to any actual magic. Her water cards fail in comparison to Aquarius and Juvia. Her lightning cards fail in comparison to any other lightning user. Saying a character has a lot of potential means nothing unless they show something to hint towards it. Cana hasn't shown anything to hint towards this progression. Fairy Glitter doesn't count as on its own it is a powerful spell no matter who wields it and the first time she performed it was easily destroyed by Bluenote.
