In games where there are guns like in Fallout, I usually prefer to use them over melee weapons. Which is mostly because I don't think there are really any game out there able to really make it interesting, it always feel either a bit clunky like in Kingdom come or as in Fallout / Skyrim where its a bit to much hack and slash. I think TW3 had an ok system, but this is obviously 3rd person combat. However the two things I really didn't like in TW3 combat is that after a while, you notice you can fight on the edge of where the enemies will stop hunting you, which is actually not very far away from where they are hanging out. That to me ruins the immersion a little bit, because its very obvious when you reach the edge of the area where they all run back. The second thing is when you fight multiple enemies they are often very passive, where some of them will more or less just stand there and wait for their turn to attack, even if they have a very good chance of hitting you. But guess that is done to give the player a chance.
But anyway, I can see how FP melee combat can be hard to make in a good way, So I just hope they come up with a new exciting way of doing it. But exactly how to do it, Im not sure. But maybe a mixture of Kingdom come and Skyrim, so you can attack from different directions like in Kingdom come, but faster as in Skyrim.
