Right now, having a high skill with tattoos guarantee that tattoos are done in less than a minute with the snap of a finger. I feel like this detracts heavily from RP potential, and there should be a better solution to reward artistry toons with high skill and stat investment.
I propose that time to work a tattoo is universal or doesn't scale as steeply as it is right now; instead, we should have chances to inflict wounds depending on how bad the artist is, akin to cybernetic surgeries.
Letting the tattoo set in and heal is also a huge part of tattoo culture; and if the tattooed character spends time being dirty or have the area covered in clothes for too long before the tattoo is healed, the tattoo being mangled would be fairly interesting too, as it would add another layer of fluff and risk management to tattoos.
Anyway, that's all. Thanks for coming to my TED talk.
