But wotan, you neglect the following:
- 190s have one of the fastest roll rates in the game. If they lose a little, they STILL have one of the fastest roll rates in the game. Even up to 200-250mph I've not noticed any degredation.
- 190s have one of the fastest acceleration rates in the game. even with heavier internal weight, you can still just nose down and pick up 50mph instantly. Or hit WEP and not have to wait at all.
- 190s are not used as turn fighters very much. Even when they mix it up in close quarters, they are usually E fighting, looping and whatnot, using the vertical or their speed for attacking and defending. Affecting the stall weight of a 190 isn't really going to change its operational envelope much, because of the way most fly the plane.
- LW guns in this game are pretty weak. To quote Nelson on a Simpsons Huck Finn episode, "Man those guns are weak. Pow'rful weak!" 2 cannon are good. Yes. 4 cannon are better. MUCH better. Snapshots where all 4 cannon hit are evident as the plane explodes or a whole wing falls off instantly. Hitting with just the 2 inboard guns can often lead to an oil leak, a missing flap, aileron, or some minor part, but taking 4 guns really makes a difference when you start seeing planes fall from the sky instantly.
So:
Added weight issues: Not a problem. 190 already accelerates great. It's not a speed demon anyways.
Reduced roll rate issues: Not an issue. The 190 still rolls better than almost any other plane in the game.
Weight increasing stall speed/other issues: Not really a problem because of the way the 190 is flown (and is most effective) in online situations. Rarely will it be flown at the stall's edge, and usually by the time you do fly at the stall's edge you've burned off a chunk of your gas, and thus reduced your weight.
Weak guns issues: 2 more guns. While they last they REALLY make snapshots hurt, and hurt bad. You can get at least a few kills before you run out of outboard ammo, and when you do you're that much lighter for it. Sure I'd love to have outboard MG151/20s but we don't have that. In their place, the MG/FF do make a stronger, more solid punch.
So I say there are pros and cons. The issues with adding the outboard guns are negligable and the benefit in the short term is worth it. The drawbacks in the long term (after you use outboard ammo) are minor, in my opinion.
Again, it's all subjective, but this is my (and some others') thinking on the matter.
