SNTNL Drones "Almighty Ordnance" needs to be fixed.

In tight spaces the missile barrage just hits the ceilings and/or walls, and only the direct damage from the missile barrage counts. Even if there's enemies at a low enough health to get killed by the barrage, the missiles could always hit the barrel a foot away from the enemy and cuck itself.
Cause & Effect, and all that. Hell, I've seen enemies die FROM the barrage, and not get action skill duration reset.

If you think thats bad try some of Fl4ks pet bugs. Its honestly baffling how buggy his core mechanic can be especially since I really don't recall having this many issues with deathtrap in borderlands 2. Countess Spiderant likes to get stuck in the ground and never come up, pathing issues, weird behavior with gamma burst if you use it with the Jabber/spiderant, and of course how bad a lot of pets are with bosses.

Jesus, I've heard some complaints over FL4K's problems from friends and what you say sounds about right...
The more I play this game the more I realize it's held together by duct tape and orphan tears.
