Yeah they will be used for gaming and also WYSIWYG. I am not that good with conversions, so I just take what they armed with. What isnt that bad because all the witchhunters have a pistol and a sword. The only real drawback is the leader with his 2handed sword (I just dont like it as much), but its not that much of a problem as he has his loyal hound to assist him.
Also I am not into the "take the best" way of gaming. Especially in a starting warband I like the thought that they are all equipped with the weapons, they had or found before.
