Those tedious aspects of painting minis: Filing off the flash, pinning the feet for a special base. Priming. The drag work. The boring parts.
If you could have a studio apprentice do one thing for you in your miniature modeling and painting practice, what would it be? This is completely fantastical, use your imagination.
For me, it would definitely be a person dedicated solely to mixing the small balls of Green Stuff I use to sculpt. I would have a far more efficient sculpting experience every time if that activity were done by someone else. Wish they had a machine to do it.
But you know what they say (or as Ian McShane as Lovejoy once said): you want something doing you do it yourself.
