Are you geared and is your party not being idiots? If those are both the case you should NEVER die to WotL. As far as I've seen every AoE in the game has a timer on it and if you miss the timer you take the hit out of it or not this isn't going to change unless they completely remove AoEs. To move on to my point I took me 5 days but I dropped Titan on a SCH in full DL minus 1 piece and my Ifrit weapon I ate plenty of WotLs from misisng timers but they NEVER killed me unless some idiot stacked them or trapped me in a stack (left me at around 1440 easy heal). Your party should have a relative idea of the rotation so you should ALWAYS scatter our for WotL so the plumes don't stack than no one dies and if you don't know the rotation so well stay spread out in general if its not stomp or the circle bombs. Don't call it game breaking just because you haven't figured out how to work around it.
