Seriously, it has consistently taken me at least 2 clips of ammo to stun an overload because it requires you to sustain fire on an enemy that just spams its teleport around you. Bows can do it in 1 hit, at least make it to where it procs on a held ADS instead of having to sustain fire on Mr. Teleporty overload champion
There is some stupid hidden cooldown in the overload mod for automatic weapons.
When your mod stops working, you have to stop firing, wait a split second, then start firing again to get the stun to proc.
In Master content where Champions will one-shot you within a moment of being in their line of sight, this really sucks.
