I will not make a long reply with all the 20 things so I'll just pick this "
12. Needler, even dual wielded, it was useless."
I was using it the other day and it ofcourse works exellent on non moving targets, but everyone is practicly moving all the time so...

But I also noticed it was good for suprise. While I was jumping into the air in Beavercreak I shot towards one of the snipers (you know where they are hiding) and I only shot like 10 shots from each of my needlers and he died really quick.
But on the other hand I was duelling vs another guy with the same weapons and we fought for like 20 sec or so in close combat, and that is...zzzz...zzz..
So what I think is that you have to killl your opponent very quick or die yourself.

So this weapon is bad sometimes and good sometimes but mostly bad. But it is fun to use sometimes I must say.
