Don't forget about the old metal/plastic and metal/metal multipart kits, meaning "it will never fucking hold together no matter how many wires you drill in", including the unholy abomination of Space Marine Devastators which had the light plastic body and heavy metal hands with lascannons etc resulting in miniature toppling all the time.
The pieces breaking off is actually a positive when used as a blunt instrument; they embed themselves into the chud's feeble flesh and cause lead poisoning, thus removing a day or two of their life.
Another con for resin: the dust from sanding/drilling is toxic which means you need to take extra precautions.
Another pro for resin: almost all 3rd party stuff is resin.
I initially had it as a positive but was having trouble coming up with a funny negative for plastic so I reorganised it. tbh the entire meme was just me coming up with the metal section randomly during the day and then trying to figure out other jokes for the rest.
Minus for plastic would be: GW apparently think it's worth its weight in gold.
daily reminder - wet sanding resin eliminates the need to wear respirators by trapping the toxic resin in liquid
please do this instead of dusting up where you live
Games Workshop, they're the company that produces Warhammer models and overprices everything. They are not good.
