That is actually the exact reason I hated Tidy plates. When the mobs are spread out and you are multidotting them the plate appears just above the mobs heads like
this. I don't think I have screenie for something like the whelps on halfus, but I'll check when I get home. Basically for something like the whelps it stacks all the nameplates into a neat column where you can easily see all the nameplates, dots and durations, and %of health (which makes it easier to spot which ones to finish off with sw: death.
ps-that screen was my first run of elvui and I quickly put it together before raid, so don't judge it too harshly
Wanted to show you what the nameplates looked like though.
