I love the Wolf.
I agree that combat encounters can be roleplayed, and SHOULD be roleplayed...that's what makes them fun.
However, I must raise a point of contension. The reason a lot of people make the afrorementioned differentiation between "roleplaying" and "combat" encounters is clear to me:
Many people STOP roleplaying when the fight begins. The focus goes away from engaging their fellow players and the DM as their character, and they become a strategist staring down at pieces on a board and metagaming the situation as an abstract exercise of tactics and numerical equations.
When you are roleplaying your character in "talking scenes," you are roleplaying because you are stepping into the skin and acting (and reacting) as that character. This can be hindered by combat in my experience...especially when there is a battlemat involved. The battlemat becomes the focus. You can watch people's eye contact vanish as they stare at the table at the pieces they were embodying moments ago. We as players become forces moving "that piece" that is our character. Therefore the portrayal of the role can, and often does, take a backseat to strategy.
When this doesn't happen and the players are totally wrapped up in the heat of the fight, and even making bad (tactically) decisions because they are so into their character is what I truly love about roleplaying combat encounters. Just doesn't happen enough in my experience. This is why I shall NEVER use a battlemat when I DM.
Down with the battlemat.
At least for me.
Bless you if you like the battlemat.
