Not using tidyplates, no. I'm using the default Blizzard UI, showing nameplates of both friendly and enemy targets, enemy targets in class colors, marks on friendly ones. Wouldn't Tidyplates change nothing about the actual problem? Because the plate itself does not necessarily indicate the characters position, but slightly above it. I guess it's just a practice thing.
I've also been telling ppl to stop moving for a while, or, if it's a ranged class, to stay near me for easier orb placing, i just kinda felt bad for making my team adjust to my playstyle
When i've been playing with mistweavers and they complain i usually tell them to drop the orbs someone near me and i'll just run into them if its not on me and i feel like thats by far the easiest way to deal with it. That'll also get your teammates used to running through the random orbs whereever they're going if they're not full hp too which is kinda nice
