Are you sure that upgrading an enchantment from rank 10 to 11 also is 5 superior marks of potency? I can't check myself at the moment in the game itself (you can't upgrade via the gateway :P )

My info here suggests it 2 Superior Marks: https://www.arcgames.com/en/games/neverwinter/news/detail/9556803-neverwinter%3A-marks-of-potency-pricing-changes
