Of course everybody is allowed to have an opinion and voice it. But the other side of that coin is that a lot of people will have an opinion on uninformed opinions posted here.
I'm not saying there are no downsides to WFRP3. There is a lot wrong with it. But "it's more boardgame than RPG" is an opinion that's posted very often on this and other forums, and that's very frustrating to a lot of people because it's so incredibly wrong. It's an impression that's very easily dispelled by just reading the rulebook. (After that, you should be left with the impression that it's a real RPG, but it butchered a much beloved setting. Also not quite correct, but more justifiable.)
