The European Championship would not accomplish anything in today's roster than the Intercontinental or US Championship could not. The roster is large enough for two midcard titles, but three would be pushing it a bit. You have the Intercontinental Championship as the true midcard belt while the US Championship can be used for Open Challenges (although Seth might do away with that, being a heel and all) or as a secondary midcard belt. I liked the European Championship too, however it is not needed today. They had a chance at making a European Championship return relevant today had Rusev brought it in to replace the US Championship during his reign, that ship has sailed. Keep the title structure exactly the way it is. There's nothing wrong with it at the moment.
