Against Ifrit (regarding evades/misses):

I've tried to get an evade off of his frontal claw attack 20 times all with +22 evasion, Light Strike, Featherfoot II, and Diversion (at the same time) with no success. So I wish people would stop claiming how easy it is to get an evade/miss for Simian Thrash in every encounter. Though, after 20 attempts to evade/miss failed, I stopped trying - at least until I can get additional +30 evasion. Shame on me, I know.

Even if we were able to evade/miss Ifrit's attacks 50% of the time, there's still a high amount of risk for taking damage from failing to evade/miss, getting an Eruption cast on you while you're near the tank (and subsequently making the tank take extra damage). Not to mention the long animation sequence of Simian Thrash (if we were able to use it) and not being able to manually dodge an AE, which is even more dangerous since we have to be right next to Ifrit to be within range.
