Many are overthinking it Lynata. The rule makes sense in both balance and real life. If you want to use it in DW go ahead, I'd recommend it (among others, but not all of OW's rules). Some have taken to defending their opinions, thus I refute them with facts.
B. I'm not too keen to false arguments myself.
You want it realistic, so do I. Doesn't change the fact others have brought up the "fantasy junk" argument many times against my comments. But I wouldn't use it against other I think its stupid; mention others using it yes, use it myself no.
The original full-auto rules are poorly thought out. A full auto gun doesn't fire 10 rounds in 5 seconds, more like 50. But the guys making the game (originally Black Industries a subsidiary of the Black Library, consisting of at least a majority of British 20 somethings) probably never seen a real machine gun outside of the movies and likely didn't know how they really worked. Which is why a weapon with 600 rpm only fired 10 bullets every second and shooting a bucking gun made it easier to hit instead of the logically correct reverse. Again they probably didn't understand this, so we get more 'soft' rules to the current effect. The attack is still meant to be the character jamming the trigger and trying to keep a hold on his gun.
The change makes a whole lot of sense on its own. Harder to hit firing full auto, as it should be. Shooting a singular someone with a full rate of fire burst at long range is, to put it bluntly, stupid in real life. The bonuses for short range and the bonuses to hit larger targets or groups of targets countering the penalty also fits together realistically with reality.
Then again there are poorly thought out rules, at least for normal humans, which make the change seem too much to some. I am speaking of course of the characteristic rules and those counting on the bonus to actaully hit stuff, or want to use full auto guns as sniper rifles (people regularly referenced as munchkins). In the abstract realm of the TT humans hitting only 1/2 of the time makes sense. Theres a lot of things going on and many aren't actually trying to hit the target. In the RPG realm of DH things are different. So in the end the problem is either from the bonuses for range or the characteristics for BS were off, which causes the heart ache for many.
As I have said earlier though, when firing automatically the first shot is invariably affected much of the time. Firing single shots you can take a lighter grasp (also known as correct) on your weapon line up the sights correctly and use appropriate trigger control to keep from moving the barrel off target, and take your time and wait until you should fire to get a hit. When you know your about to do something which could make the weapon jump out of your hand you WILL grab the weapon with a much stronger hold. Only an idiot, or someone who just loves black eyes, will use the same kind of sighting methods (for the same reason you NEVER put your eye directly onto a scope), more than likely not use appropriate trigger control, and just let loose without pause at first opportunity. All of which ruin your accuracy.
Nevermind the issues with firing 2-3 1/2 second? bursts in 5 seconds with pauses to "re-aim" taken in between. Honestly, not trying to be mean here, but it sounds like you're just making this up to justify your position. This never happens like that in real life. Simply firing carefully aimed single shots is much more efficient, accurate, and effective.
Thats enough for me though, think I'll call this quits unless someone has anything new to inject.
