I do like the "nominate for rework" thing better than full-on delete, but...
Rosette. It's so busy that it literally makes my head hurt to look at. I mean, it gave me good empathy practice, but... yeah, so many teeny tiny circles... Hypnotic on many breeds has the same effect, but there are a few color combos for it and Jaguar that are okay so like, I'd give them runner-up status.
Keel or Squiggle for terts, both are really hard to work with (Keel looks painful, Squiggle is just ten times busier than basically any other gene onsite besides Marble/Mottled).
Y'all saying Capsule and Peacock are killing me
Definitely wouldn't mind a Capsule transparent-bits rework to make it more clearly the lore it was given on release- a
thin layer of fluid on a dragon's belly- but it hits that sweet spot of working with both the shiny genes and the flat genes for me and the accent colors are awesome ^-^
...if you're using Peacock on a triple, imo you're probably using Peacock wrong. In my experience, it's best for when you're trying to wrangle an unruly tert and checking for anything that could save it.
Can't defend Stitched/Patched though. I feel like part of their problem is that the resolution is super tiny? So like, they don't feel like they match the
scale of the other genes, if that makes sense. They're great for the prosthetic/artificial dragon vibe, though.
