Look - a Gatling gun is a great weapon, if you want a splashy show. It's massive, it will kill anything in it's wake - but it's still massive, requires a great deal of resources to acquire, and it you can't set it up before you, yourself are shot, then it's valueless. 

All it takes is one bullet - one kill - to stop you. And it doesn't need to be from another Gatling gun. In fact, a rifle will do the job better, or a well aimed handgun. They're quicker, more adaptable, and all your opposition would have to do to win-

Is to draw first.

Infinite is only useful if it's faster than the other guy's toys - and in we were to duel with these, I would win more often than not, if only because I will draw my rifle before you set up your contraption.

Not reacting poorly here was a good choice on your part, and it's an improvement on your prior behaviour. This is a functional combo, which is why I'd said as much - but the goal should always be to win, first, and fastest.
