I was curious as to why Light Strike and Pummel requires 10 and 20 mana respectively, while the other DoW classes have no such resource requirement.

Light Stab (increase accuracy)
Heavy Stab (increase enmity)
Heavy Slash (increase enmity)

Broad Swing (conal attack)
Heavy Swing --
Full Swing (conal attack, increase enmity)

Multishot (extra shot, 15 seconds)
Heavy Shot (reduces target TP)

Heavy Thrust (bind)
Pierce (damages enemies in line)
Full Thrust --

Light Strike (increase evasion and physical defense) 10 MP
Pummel -- 20 MP
Flurry (extra attack)

What justifies it?
