Seriously, what is the issue with the Silverback now?

So, since I’ve been trying to beat the new hive on several occasions and been screwed over by this more than once…

What on earth is now wrong with the Silverback? The Tri-Shot has been turned into an inconsistent mess of a weapon. Sometimes it decides it will do full damage and overheat and cool down normally, other times it will just overheat within 3 seconds and barely do any damage while taking freaking AGES to cool down even when I DIDN’T overheat the weapon completely, and basically being a complete waste of a weapon to fail runs with. Why is this necessary? What is the reason behind that?

God this is annoying.
