Well, if it IS tied together, then specialty abilities Like Lumbering and Whirlwind-Devil should probably coded in, usable as a modder source, as well as allowing said values to be altered (to make other such traits). A minor issue though. For the most part simply having more hitpoints makes more sense to me ... in an odd sort of way. Of course, in the system I am used to, most units have 1 HP, while elite "base units" have 2 HP, and a general could have as many as 10 or 20 HP (but usually less than 10), and all general bodyguards had 2 HP. I think War Chariots might of had 3 HP for some odd reason, while Chariot Archers had 2 HP.
Regardless of where I am conceptually "coming from" I don't mind the new HP/Strength system, although I think there should be a "speed" stat. I think having a speed stat is A) already going to exist, and B ) could represent the relative rate of attack based upon HP.
For instance, having low speeds would imply 1 attack regardless. (or 1 for every 100 hp), while having extremely high speeds could mean 1 attack for every 5 hp. Or something like that.
It could be a very simplified system, where speed is from 1-10 (or it could be called agility, and movement could be separate), where 1 speed has 100% slow, 2 speed has 80% slow, 3 has 70, 4 has 60, 5 has 50, 6 has 40, 7 has 30, 8 has 20, 9 has 10, and 10 has 5% slow. Where the percentage is 1 attack per round based on that many HP in relation to whatever 100% ends up being. We could have 100% to be 100hp, or we coudl have 100% be as low as 20HP, where an agility of 10 would net you 10 attacks with 20 hp.
Now, Obviously there are more sophisticated ways of making the system work. In any event, I think we should try it out at least into the next beta, where there will theoretically be multiplayer battle-betas. In this case, we can address the various elements of battle with a little experience using the new system under our belts, before we simply think that HP is a "health" mechanism.
I would like to see the Strength/HP system work. I do hope that morale, at least, is also added in. (with endurance being the other one, which is slightly less important than morale, but still quite important)
