I think that a Rider style of play can be a really fun class concept to utilize, not going much into the specifics of it, I think that it should honestly be a promotion class for Soldier yes yes. It also is fitting to Sigrogana lore too (Wyvern Riders being based in Alstalsia) which is real nice. And lends into theming that a Rider might like with a mobility/tanky playstyle.

That said if there should be a emphasis on mobility, I'd like for it to be mostly delegated to gap closing attacks and long distance striding through the usage of bonuses like Charge, it could even play on this by having a passive that removes the movement penalties that Heavy Armor suffers.

Just spitballing anyway, +1 to the idea, as I think a Rider would be a pretty sick class addition to the game.
