Oh yes, I use the 110 Penetration of the Dakka Slugga. I'm not really sure what your point is though, no ones getting one shot from Pistols on non melee or even melee classes. Great finisher though.
omfg, this is still a complete lie. Knives and Knuckles do double backstab damage on power attacks, not triple. EDIT: NM I get what you are saying now and you're right, they have a different backstab multiplier and that is weird. I guess it's to slightly curb the one shotting it would cause if all weapons had the same x2 multiplier, but why give ranged infantry such a big bonus.
Tactical or equivalent melee weapons (daggers, knuckles, ceremonial knifes) do x2 backstab damage, while the other melee weapons do x1.5. Imho, it's some way to represent that it's easier to slice (crunch? not sure about knuckles) the throat/brain/whatever through a weak spot with a knife than with a chainsword or other more heavy weapons when the victim doesn't see you come. You know, assassin's creed mode. It's not very gamebreaker right now...
You know, the assaults feels less manly when approaching from your back :< (their weapon is bigger but the smaller one does it better).
...I wouldn't necessarily say that. There is an Ork weapon that you can unlock via supply crates called the 'One Shot Slugga". I haven't tested it too much, but if anyone's shields are down, it's very likely to kill them if you shoot them, especially if you shoot them in the face. It does have a 3-second reload and only 1 round per reload though. You can; however, dash-attack an enemy with something like a Stormboy which takes their shields down and then shoot them once (just don't miss!). It's a pretty nasty 1v1 combination, though it's not all that good in a prolonged fight...works nicely for assisting every few seconds on targets at medium-range in fire-fights though. It may or may not one-shot low toughness characters with a single headshot through shields, but I'd need to do more extensive testing, also not sure if it does any more damage from behind or not.
Okay so 335 damage is a lot but the regular axe choppa with a damage mod does 350 on the back. Think it's 250 in the front and 140ish with quick attacks. Knuckles doesn't even break 100 damage with fast attacks and the frontal power attack does a pitiful 150ish. Elektrik Choppa will probably be doing a ton of damage whenever I find a damage mod for that thing. So shootas getting more damage on one attack isn't that big of a deal if you ask me! Sluggas are pretty comparable to shoota damage. Hell, the dakka slugga does more headshot damage it just has less ammo and bigger spread. There's a little overlap here which isn't a bad thing. Helps keep things a bit more balanced.
