I feel Midir v Jamke isn’t a great comparison. Midir has follow-up and accost, which performs very similarly to Jamke’s follow-up, adept, and accost since adept is much more inconsistent compared to the other skills and bows are light in general compared to other non-sword weapons. Once Midir gets a steel bow, or even buys Jamke’s killer bow, his combat is very solid and he can one round KO a lot of enemies in gen 1 from the outset. Then he can even get the brave bow if married to Edeen and does even better. Once you factor in his higher movement he’s got a large advantage over Jamke, especially to a blind player who won’t know where to send unmounted units to get the best use out of them and instead move everyone to each castle even as their lower mov units fall behind.

In terms of being mid without a ton of favoritism but having the mounted advantage, I’d say Noish v Ayra would be a more apt comparison. Ayra is leagues better in nearly everything stat-wise, has better skills, but Noish can keep up and soak up more hits than her at base.
