I understand he has horrible matchups, but he actually has a playstyle that can be considered safe. His aerial arbiter is a hit confirm for his lvl 2, so he doesn't have to rely on his punishable neutral square string for kills. He can also combo off of his aerial arbiter, and if he's close enough, can get a ap burst combo off of it.
He has a lot of safer options than most people notice. His "natural" approaches are extremely punishable, but he can dismiss them from his playstyle completely and still be considered competitive.
I don't think he should be moved far up the tier list, but he's seriously looked down upon simply because of, imo, his neutral square. He belongs in at least Low tier.
I don't know how to calculate the matchup data, but I believe Dante at least dominates the bottom, low tier characters. --- PSN: Lakizzle23 Mains: Dante (the best ever) , Good Cole (starting to suck with him...)
