There's just no way I can test for the same damage 3 times. I don't have anything that can hit hard enough for static dmg. Atonement is about the best it'd get, but I have to build enough hate for it to hurt first, then catch Ard's hate up. -.-
Usually, I even martel and ard's hate out, then start tests from there. I've caught a lot of potential issues right at the start like this. A missed piece of enmity +/-, etc. So, I have ard pull with a 1 CE action, then martel does flash, enlight, cure for 0. at this point both are at 201 CE. and I check to make sure we're even by casting 0 CE actions and making sure the mob stays on the last to cast.
And whenever a given test is completed I can just test that we're even again, then start a new one without having to pull again.
The biggest issues I run into, are;
Losing count while spamming 1 CE spells. I could really use some 5 and 10 CE actions... I suppose I could make a 10 CE action via -50 enmity gear. But I'd have to start macroing gear for that. Time to make a whole lua file for enmity testing sets! ugh....
and Taking dmg. Either cause phalanx wore while I was spamming on ard, freak crits, or ard going over by too much SS breaking before martel pulls it back.
Quantifying dmg taken enmity loss would do a great deal to help. Then I could simply note the dmg taken, and my max HP, and continue the test. And then factor in the enmity lost afterwards.
