Having higher level gear shouldn't BREAK coil runs!!!

To add room for error, of course. You pretty much got your answer when you mentioned the fights being toned down for a lower ilevel. Their obvious first intent was that the method for Savage was the intended strategy, but they modified it to make it easier and add room for error.

Correct and in the same moment as they added that "room for error" re-voicing a renaud became an intended mechanic design. As you just clearly stated yourself the devs KNEW that this is possible and added it because of that.

You clearly missed all the posts when LX launched from people who were obeying all the mechanics properly and still wiping to his enrage if you drop him too far below 20% during second spumes. That's after killing all of the spumes, so don't even try to pretend it's an issue of trying to burn the boss and ignore mechanics.

That's caused by multi-dotting/dpsing levi too hard WHILE the spumes are up. At this point you're clearly supposed to bring your dps on the spumes and not levi himself (ofc some classes gain a higher dps if they also multi dot on levi for example). But you're definitly not forced to do a full dps stop like in ifrit.

Levis spumes spawn rather quick in comparison to ifrits nails that gives you the possibility to switch your target in time to keep dps up all the time without pushing him too early. Ifrits nails have a certain delay which forces you to completely stop dpsing.
