I'm tracking this thread closely because it's something I intend to house rule as well.
I'm not here to rain on 6E because there are a lot of things which are interesting and that I'm eager to try. But, for both game balance and realism, I don't like that an unarmed troll can lower his or her DV by picking up a weapon.
I've had the same debate in my head about how to scale damage, especially when light pistols do 2P and heavy pistols do 3P. But, at the same time, given the range constraints of melee weapons vs. ranged weapons I'm not sure it's a huge issue for me. But there are secondary ramifications, like how to scale the damage of thrown weapons, which don't have the same range constraints as melee weapons.
Not that I want to add more rolling, since we're trying to streamline things, but one thought was to roll Strength and add the hits to the base DV. The problem is what if you have an above-average roll and all of a sudden the Strength 8 ork is adding +6 DV to an attack, which is potentially catastrophic to a target now that soaking is Body-only. But maybe that's the one-shot attack that people are looking for. I'll probably have to roll through a few encounters to see what works best.
