Avengers Thor is in the same boat as the DX12 Batman. He can look really good if you're willing to modify the crap out of him.
No, you really don't to modify anything. You can change the arms if you want, and remove the sleeves but it is not necessary and it hardly constitutes anything 'major'.
Out of a line of outstanding figures like how the Avengers ended up, Thor is probably one of the best ones - along with Loki.
