Varient human while it will not be impliment based on what we hard would balance humans +1 +1 a feat and a skill the feat alone would make it worth it balancing it out even with loss of a stat point you could take a half feat as its termed to balance that out.

Half Elves and shield dwarves it should just be optional to keep the classic ability point spread. So they have a reason to be chosen over there counter parts in a class or 2. Getting additional weapon skills does nothing for a large number giving humans the same stats +1 skill same boat not worth even considering. Because they are just strictly not as good as other races without options in some classes like wise with giving half elves the same weapon feats. If that was correct on the charter builder.

3 races got hit. While they might want to play a specific class more so its about balance. The choice to leave half elves and shield dwarves doesnt hurt anything and a feat vs a couple of abilities isnt enough to deter another race it just gives Choice. +2 / +1 buffs other races in a way but those 3 races lose out on what they have that makes them a solid choice over another race in at least 1 class. Weapon and Armor Skills carry 0 Value to some classes as they already have all those weapon and armor skills.

@Volsalex Gith Also gain a movement advantage of 1.5 M Spells + additional movement makes the GIth Slightly better than shield dwarves in melee with changes additionally the weapon skills and armor basically is just a 100% loss vs other dwarves in some classes. While you can argue Extra HP and resistance in a class is better against casters than higher ac in mage on mage fight.

Weapon Skills have no Value to Barbarians, Paladins, Rangers, Monks, Fighters
Medium Armor: Warlock, Wizard, Sorcerer
Light Armor : Wizard, Sorcerer
Any class that would want to use a pole arm is already skilled in it. The classes that would want armor skills there are 3. The other classes that it could help would not use the armor skills. Thats the weigh in.

@Volsalex again Resistance has value and depending on your build tiefling like you said may have fire resistance but there spell is also fire damage fire resistance is the most common resistance. In addition to synergy with vulnerable status when the wet condition is applied to lighting and cold damage.
