Kinda looks like Wakfu. Show based on French MMO with the same name.

Could someone explain to me why snap has such a bad reputation?

This is a very good description of the system, and it very nicely highlights how needlessly complicated it is, and how inconsistent GW is about it. Love your explanation, thanks for sharing! It makes me wish 40k would use d10 or d12 (or d20) to accommodate all the nuance. However, this would only add to the overall lack of clarity.

Amazing piece of artwork. Thumbs up!
