"Your logic assumes that every artist then won that award."
"The difference between WoW concept art and ingame is enormous."
Yes, that's my entire point: if someone says a game looks bad, you can't just respond by saying they have good concept artists. That you left out that it's the concept artists that won the awards, leaving the implication that it's the people actually making the in-game graphics that won awards, took it from logical fallacy to deception.
Be clear and succinct to avoid getting caught in a falsehood.
edit: Daniel Dociu can direct style all he wants, but much like the acting is ultimately up to the actor in a movie, the quality of art we get in game is ultimately going to be up to the talents and abilities of the 3D modelers, animators, and environmental artists, not the concept artists.
