You drag mimics to a wedge/corner, and when they start casting you just break LoS, which is the same than you do with a lot of other mob lethal abilities. Infatuation is also a long cast.

Anyway, having played PCT quite a bit in there now, I feel that it's probably one of the best suited job toolkit design for deep dungeons unironically, with all of its adjustable moving parts (and of course repainting between every fight...). I haven't tried VPR but I'd assume it's actually very similar. See, this can be definitely put on a scale depending on the job, and some jobs like BRD will just want to gouge their eyes out with how the songs work for example. It's with that type of content that you can see how all the thought process for job design in XIV pve is fully focused around standard pve duties (trials, dungeons less so), but not on everything else: overworld/fates, deep dungeons, diadem/eureka/bozja, questing, etc...
