I really don't like the Blaze Turrets being able to penetrate walls. I can't seem to avoid taking damage when killing them.
They've always been able to do that.
Your sprint button is your friend when dealing with those guys. It also helps to lead their shots to positions that make it easy to pass them by.
Ya get used to them after awhile. Besides, there's much worse threats later on. That cant penetrate anything.
I might knock the turret's HP down a bit further though.
