Before we go in to this I want to ask you a simple question, if you had the bark moduals for one of the two guns, but neither of the guns already, which would you chose, or which one did you chose? Just answer me this.
I chose the catalizer.
Now the suggestion, I suggest that a slight change is made to the catalizer as it is one of the lesser used items in the game, I have only seen one other person in game use the weapon or any of the weapons in the series and for good reason, that reason is the pulsar, as a player will be some what forced to compair the two weapons to each other and to be honest, who didn't find the gun that did more dmg the farther it traveled AND explodes on its own? I did too. So obviously most people would pick the pulsar over the catalizer for obvious reasons, so to even the balance between the two I suggest a slight buff to the catalizer guns as a whole.This buff is that the explosions caused by one catalizer charge shot will set off other charges if the enemy is whiten the explosion.
In theory, this is supposed to happen already, but I think the explosions need to make contact with the charges, rather than the enemies the charges orbit.
I chose Catalyzer first, too. I think most people in my guild have one.
