...You can't argue they don't think str matters b/c unarmed is str based. Thus we are left with ridiculous system reality of a str 9 troll picking up a great axe and suddenly doing less damage then when he punches someone. If that doesn't bug you then there is just no helping you, cause you ether just won't admit it and/or you're going to blindly follow the system regardless of what is said.
Well, yes I do agree that there's a problem with doing less damage with an ostensibly lethal melee weapon than without one via an unarmed attack. Granted, you have to have superhuman strength for that to be an issue... but since superhuman strength is so easy to achieve for a character yes I agree this is a real problem in the rules since it imo reasonably goes from being an uncovered corner case to being legit problem. Should your DV go down because you picked up a weapon? On that, yeah I agree there's an issue. I'm a lot less vocal on that aspect because what I might be able to add to the conversation is not something I can talk about publicly. So I've been trying to avoid that angle entirely.
That's a related concept, but still distinct from what I HAVE been defending: fixed weapon DVs that don't reflect disparate physical capabilities. I'm fine with fixed weapon DVs because
1) STR was already marginalized in 5e melee combat... if you were a melee specialist you had little reason to use anything other than a Monofilament Whip and/or Stun Gloves.
2) If you are willingly engaging in close combat, odds are excellent that you meant to do it and you built your character for it. If you didn't build for close combat (say, you're a fat nerdy decker) you're probably attempting something OTHER than close combat with a nearby enemy. Like, oh, running away? Bricking drek? Anything BUT trying to take him on in a knife fight really...
3) If you have drek for strength, you probably don't have drek for Agility. Which in broad strokes, is "just as good" for causing meaningful damage. What you lack in power, you gain in hitting something vital. It's good enough for RPG purposes. anyway. (The assumption works less well on things unlikely to suffer "critical damage" like barriers, but still I'm fine with the idea in the name of streamlining. YMMV. If so, go ahead and give a DV penalty to someone trying to use a weapon to chop through an armored bulkhead with 1 strength. It's well within the spirit of the rules.)
