To each their own, but I just don't dig it. D&D has always been a cerebral game and about immersion into whatever character or world you happened to have created.
This combat/art style completely destroys immersion (IMO). Watch the current character class videos and you expect to see a bubbles pop up filled with "BAM!" or "POOOOOW!" like the old sixties Batman show.
Combat is so over the top and exaggerated it looks like Marvel vs. Capcom or Street fighter from back in the day.
If you like it, more power to you. But there's very little room for the "R" in "RPG" when you swing your sword and it looks like there was a small thermo-nuclear detonation.
It saddens me they took the "RPG" out of THE "RPG".
