For ray of frost (215% weapon damage):
Over 2 seconds:
Weapon A hits 2 times for 215*2= 430 damage at a cost of 40 AP (+20 regen, actual cost 20 AP)
Weapon B hits 3 times for 172*3= 516 damage at a cost of 60 AP (+20 regen, actual cost 40 AP)
Weapon B does more dps, but consumes more AP.
Very wrong. The weapon B in your example deals 20% more DPS (using weapons different in dps in an example is a very stupid thing to do btw.) so it is already 20% better. Now add 20% damage to your weapon A in the ray of frost example -> it also deals 516 damage. Regardless of the attackspeed, RoF always deals the same DPS but costs more AP.
