Once finecast improves you assholes will praise GW for it. Resin, once it gets high quality, will be far superior to metal in every way. If you drop a resin model, it will usually be fine. Tip it over and there will be no damage at all. If you even tip a metal model over, it breaks. If you drop it on the floor, may the Emperor help you, because its going to be Chaos finding all the parts again.
I've said it before and I will say it again. Plastic was utter shit when it first came out too, now their plastic is phenomenal, and is lightyears ahead of what most other companies are capable of. Their resin will get to that point too.
