Can someone explain to me the issue exactly. I'm not 50 yet. I've only done normal Ifirit at level 20 and I've watched a few videos of the HM version in an attempt to understand the differences. I'm not getting what's different about eruptions that you can't get out of them before you go boom. Why is it that in HM you can still walk out of plumes but you can't walk out of eruptions? What new mechanic is there that I'm just not getting?
