There seem to be 2 things coming out of this thread - not every human moves at the same speed and there need to be more tactical options for using movement in combat.
The first can be addressed by applying modifiers to the base movement speed:
- Reduce base Reflexes score for wearing armour
- One's base Reflexes score modifies one's base movement speed.
- One's Evasion score adds to base movement (giving Assassins and Barbarians a slight edge in speed)
How might this work in practice? Without playtesting or doing much research on how fast humans can move, possibly something like this:
- Padded leather has no modifier to Reflexes, but hardened leather reduces it by 1, chain and ring mail by 2, and plate by 3.
- Attack, Defence, Evasion, and Stealth modifiers are based on the character's Reflexes score after modifying for armour.
- Base human speed is 6 + Evasion in metres per combat round (note that Evasion may also be further modified if armour reduces a character's Reflexes score below 8).
- Speed is further modified by Reflexes (again, after any armour modifiers to Reflexes):
- 3-5, -3m
- 6-8, -1m
- 13-15, +1m
- 16-18, +3m
- 19+, +5m
Consider a 5th rank barbarian in chain armour with a Reflexes of 13. Chain armour modifies that down to 11 and results in an Evasion score of 6, meaning the barbarian can move 12m per combat round (base 6m, plus 6m for Evasion). If the Barbarian tore off his armour to run away, his Reflexes returns to 12 (+1 to movement and +1 to Evasion), which means he could flee at 14m per combat round.
I use a skills system in my games, so would allow a "Running" skill that improved movement rates in combat (and would have non-combat uses, too, of course).
As for the second aspect, additional tactical options for movement, maybe some skills of the mighty to enable warrior professions to move more than a quarter of their movement and still attack (and perhaps split that increased movement, so they move
through the attack and end their turn outside the range of an easy counter-attack - consider a "charge" manoeuvre to double the distance that can be moved and still attack, and later supplemented by a "charge through" manoeuvre that further increases movement in combat and enables an attack to be made at any point during that movement. Having a warhorse, of course, should mean you can already do this, of course.
Thoughts and builds are always welcome!
