Good for you? Ifrit is the first primal HM you technically fight (in both versions of the game) so of course it's a higher possibility that people will wipe to it, especially the "ignore all mechanics" players.
The only 2.x HM primal I see wipes to anymore is Leviathan, and that's only due to someone failing or overlooking to click the thingy in time (the timing for it is different/stricter compared to the EX version because there's no Spinning Dive before Tidal Wave in the HM version, so that is a potential cause for it too). Even then, I have only seen it happen once per group at the most. It's rare that all 8 people survive Titan HM but ever since 3.x I have yet to see it reach a point where it becomes a wipe.
I've seen people overlook killing the nail in the very first Ifrit fight (where it is excusable, because that is a fight for new players), but never in HM.
At any rate, your comment about Ifrit HM (which I don't feel is accurate to begin with; it takes a really special group to lose to Ifrit HM, even back when the fight was actually relevant) really has no relevance to t13's difficulty. Edited, Jun 7th 2016 12:14am by Fynlar
