The Elidizenos fight had a somewhat tight DPS check, and it was really the only way to lose that fight. You would almost have to deliberately stand in all the AoEs for him to win through submission. I am quite sure that whenever we face him again in a solo instance, even if it is really easy for you, there are still going to be some posts on reddit and perhaps here from some players who are having trouble with it.
I did actually only manage to barely scrape by on my NIN, and was simply to stupid to do anything meaningful on SAM XD. But eh, I know my limitations and bad skills well enough to not be surprised by it and have for a change better things to do than complaining. The only tedious part is re-doing the previous solo battle before the WoL arrives again as it's a kinda slow progress.

Anyway, I'll see what happen. Even if Zenos won't manage to "impress" me as long as the MSQ intself remains "fun", I won't complain... ... ... probably.
