Thoughts on dark seal?
Building full AP items on WW seems kind of bad, but passive and Q have pretty solid AP scalings 100% on Q and 10% on passive. Is there any math, or does anyone know how to do the math on when Dark Seal becomes worth it? The item is gold efficient on its own, but WW doesn't make the same use out of AP as say a karthus.
AD is obviously better than AP, (boosts auto damage, Q damage because Q procs on attack, and R damage because on attack procs like 3x plus 167% ratio). But a 10 stack dseal is definitely better than a longsword. Where is the cutoff?
