I'm relatively new to the game, and have been playing your mod and am utterly impressed. It's incredibly fun, the quests (the few implemented at the moment) are extremely fun and pretty challenging. I love how each faction is pretty well-balanced. I have been using the Planelords a lot lately, as they seem to be a primarily ranged faction I tend to use them defensively. It's good fun and the strength and weaknesses of each faction make this mod not only challenging, but very entertaining.
Also, to add to your research as per your reuqest:
1. In full-charge on horse back, it takes about 20-40 seconds on open planes. Infantry tends to take considerably longer and has taken anywhere from 1 minute to 4-5 minutes (with hills.)
2. On average, in this mod, since I use the planelords as a primarily defensive combat style about 7-13 minutes, depending of the size of the enemy force. With a cavalry heavy army, sometimes under 5.
Also, it seems you've already developed some kind of arrow effect for the Planelords, but I was thinking something simple like a flaming arrow. Increased damage per shot, or maybe a little damage over time effect from the fire. It seems you've already developed 3 abilities for the Planelords, I'm happy read it! I look forward to some form of epic artifact in the form of a bow or 1-handed sword from the Planelord questline.
Great work, the amount of effort and time you put into this mod really shows with the extreme amount of depth in the wolrd you've created not to mention the lore behind it. The amount of detail in this mod really legitimizes it I think. Well done, I'm impatiently anticipating the release of version 3.
