1 gcd vs 1 gcd is the comparison I made. If I was simply using Eukrasian Diagnosis to then use Toxikon sure that would be inefficient however I am using the shield anyway and already have the addersting charges so why would I cast Dykrasia for less? To assume I said alternating Ediagnosis and Toxikon is a dps gain is sort of bizarre when one isn't a dps skill at all.
