I feel that compared to PS/Athletics, Ironflesh is slightly worse and WM is much worse.
Mainly, I would like to have ironflesh and WM almost as important as things like PS/PD/PT, Riding above 3/4, and athletics. Oh and shield, too -_-.
For me, I would like:
1. STR + 1 hp for every even point
2. Ironflesh +4hp (average hp increases by ~5 at max IF), or +3 hp (average hp drops by a ~5 at max IF),
This properly boosts IF without changing natural HP levels too much. This hurts builds that don't put points into IF.
3. Halve free WPF (natural WPF or WPF with 1WM would give ~60-80 proficiency points)
4. Agility gives free WPF (18 agi should give enough free WPF for a level 30 as it does now, ~110 or so)
By giving free wpf by raising agility, it equalizes itself over strength, and buffs further use of raising agility slightly.
5. Lessen the slope of high WPF or some Weapon Master Buff
Make it so higher levels in Weapon Master actually mean something.
This is difficult because one does not want to make it too punishing for hybrid builds.
Increasing the amount of points you get from higher WM levels could work fine, although slightly lessening the WPF curve would be appreciated.
Overall, it would be a nerf to strength users' weapon speeds while increasing durability with +4 hp Ironflesh (I had +3 first option, but felt that that would have been too big a nerf), a few more hp if IF is maxed. Might nerf high strength ranged with less free WPF.
Balanced builds would remain relatively unchanged, since their str and agi would balance everything out to be comparable to how it is now. They may be able to get higher wpf due to the weapon master buff, though. Medium agi, low WM builds will still be faced with a population that has higher WPF in weapons on average, so higher WM will be more helpful than before.
Agi builds will be buffed, but they really need to max their IF or they will be even more fragile. Ranged would be more accurate, yet people may have a few more points hp on average.
Builds that sacrifice skill points for an extra point in PS/athletics or something will get nerfed. They will still get 1-2 hp or some proficiency points out of it though just from the +3 str/agi.
