I don't really want to "do away with TB", per see; I would like to readjust it and have it apply to something other than "skin-soak". Whereas Strength Bonus (or, in my homebrew, Agility Bonus for some weapons) makes sense in applying to melee weapons, I just don't see the sense of Toughness Bonus applying to a soaking mechanic.
Probably because I've played in other systems which used similar mechanics, so I don't have any problem with Toughness applying to soak. To my mind it follows exactly the same logic as Strength (or Agility) applying to damage. If your physical strength influences the amount of damage you can deal out, then why not you physical toughness influence the amount damage you can take.
Because while Strength allows you to hit harder with a weapon or Agility allows you to place your blows between the chinks in the armour, a persons Toughness or physical Endurance doesn't really make you take less damage from a bullet or make it harder for a chainsaw to tear into your flesh.
I have no idea how you can say that those things share logic.
Do elephants have AP5 skin? No,
Can they get hit by lots and lots of 9mm rounds before dying? Yes.
What's the issue? I really don't understand it. An injury that has been reduced to 0 by TB hasn't "bounced off"; it still drew blood etc.but not enough to matter.
My TB of 2 protects me fully from splinters and cat bites.
Except that if I stab you with a knife, you're going to take the same amount of damage as an Olympic athlete would take if I stabbed him. If I shoot Uri Geller in the face, he's going to be just as dead as Bear Grylls would have been if I had shot him.
Yet no-one of sane mind would argue that Uri Geller and Bear Grylls are just as tough.
Why does Toughness Bonus work like 'skin armour'? The short answer is 'tradition'.
Longer answer: FFG doesn't have free reign to do whatever they want with the WH40KRP range. They have to conform to the terms of the liscensing agreement with GW, which states (or so I've read in other threads) that WH40KRP has to maintain clear lineage to the original Warhammer Fantasy Roleplay game. Hence, percentiles, gory Crit Tables and, yes, 'skin armour'.
TB damage reduction doesn't really bother me, because there is some precedent for it in real life. We've all heard stories of badly wounded soldiers ignoring their injuries and carrying their fallen comrades to safety, and we all know people who act like they are dying when they stump their toe. Different TBs at work...
That all sounds like a bit of a stretch. This might have been true in the original Dark Heresy, but since then, a lot of things have changed. I would find it odd if the WH40kRP line had to conform to a very specific set of rules but be completely free in all other regards, and that TB-Soak would specifically be one of those set rules. After all, the line has done away with a great many things and are quite far away from the Warhammer Fantasy Roleplay ruleset now, with Black Crusade and Only War; and let's not even discuss Dark Heresy 2nd Ed., where the first betas clearly decided to throw the baby out with the bathwater, not to mention the whole bathroom and the kitchen, too.
I do think that TB-Soak is something that did carry over from Warhammer Fantasy Roleplay, but that it would be due to licensing agreements is ridiculous, if you look at all the other changes they've made to the line. I think it's something they just brought over without thinking it over, when WHFRP became Dark Heresy, and then it stuck.
he put almost all his experience into toughness
How the hell did a Commander end up with a Toughness of 90+? o_o
I like the Idea of increased wounds instead of damage reduction, it basically preforms the same role but there is more of a threat to the character. My group has a commander with a toughness of 90+, I have begun to shift away from combat to more narrative challenges to balance this out but most of the stuff I send against them cant hurt him very much.
That's still only +20. With +5 from his Specialization, he still needs some way to get 65 Toughness. Even assuming that he got a straight-up 20 on his Characteristics roll(s) or that you're running a statline with 20, that still leaves at least 15 Toughness unaccounted for.
And I can't think of a Regiment options combination that results in +15.
