rather than look at dps numbers for the most rng affected class in the game as far as parses go, in 2.x i simply just got the average damage of DE, compared it to the average damage of AE and then found the dps gain/difference if i simply replaced all the DEs with AEs using the average. most of the time it was around 2%. not sure if there's a flaw with that approach, but +30 from not having eye applied seems a bit high (you'd DE like, 10 times or so in a 3m parse? 600 potency wouldn't spike your DPS up by that much in a 3m parse)
