That's not "talking against it". That's weighing the pros and cons and being nuanced.
Yes it is. Breaking it done it's the following. (At least as I've read it. Your interpretation may differ)
1. Action games have good combat for action games
2. So do RPG's need to be more like Action games?
3. No, it's not as easy as the systems in a role-playing game are much broader
4. So, what does the combat need to be? We have to find that out.
Again, I bet you whatever Obsidian's working on, it won't (directly) copy other action oriented games and diverse systems will still play a big role in how to play the game (for good or worse)
