This idea is easily seen as bad, from anyone with a little bit of knowledge.
Doing such change, would grant Fighters and Swordsmen a bonus of atleast 70 crit rate (70 passive + 70+ base), thus, granting the crit rate cap (80) to both these classes, same for ultimate majins who have a 70str/sol passive, granting them cap crit of both physical and energy.
And as for any Guard change... first of all you should know that Guard was hidden changed and gives a 25% chance to block anything thrown at you, if you were to spend just 2 SP into it... 2 SP and you will block 1/4 spells thrown at you.
the idea of Guard and a damage reducer and not a chance on so many to undo.
he powers his physical defense and energy defense during the guard's hold, based on the defense rate, giving 100% anti-crit and anti-knockdown, and the ability to counter attack by skill level.
Taunt running on players (this idea is because SK has anti taunt and mobs do not have taunt)
Soul = 1% energy atack
Strengh = 1% physick atack
for a good attack if a good defense.
