Strategus COMPLETELY REVOLVES AROUND HEAVY ARMOR late game.
Yeah man. I think that even late game, Plate Armor should be pretty rare, with Leather based armors being the most witnessed on the battlefield. You could probably make a realism argument here, too, if you wanted; armies outfitted with leather would be less expensive, easier to produce in a decent amount of time and easier as an armor to carry on the march. Of course in that same argument Chain would be more expensive and take longer to make than plate. In either case, for balance in the game, Chain and Leather really should be the most witnessed on the field.
That fact is that agility needs a lot of love, too. Strength gets damage, rad, it
should get damage. Agility gets mobility, that's also a good fit. But strength also gets endurance, extra health and the ability to wear greater armor. This really shouldn't be the case, unless agility is also going to get either an endurance or damage benefit out of it.
Perhaps the new WPF curve and the way Weapon Master will work will allow prof high enough to more drastically alter damage, which would help to better balance Strength and Agi. Agility gets mobility passively and through Athletics with most damage through WM; Strength gets damage through PS with protection through IF and passively. That could work nicely.
15/27 was a really fun build in regular play, but in Strategus it just wasn't viable against a horde of plate, even with picks or maces. 18/24 may not be much better, but here's hoping. In most fights I also have to consistently go above the armor I feel comfortable wearing with athletics. It's not especially fun. My only major grievance with this module is the armor levels, and I know a lot of the dudes who are still just playing Native or other mods feel the same way. The real disparity between strength and agility only comes with heavy armor.
