All yesterday during mayhem rumble (no level advantage), it took me two direct (to the face) hammers to take out defenders in their bubble, blade dancers, and storm callers. As I am doing the imprecations quest at the moment, I will probably be playing it again today, so I will try to remember to record my encounters this time and display my proof of the matter. FYI, if I am not using max armor with that solar armor chest perk, I am typically one shot by gunslingers. When I use gunslingers, I often find that I can one-shot about 50% of titans, but I expect to 2-shot them every time. Edit: forgot to add that buffing golden gun damage reduction is fine by me (as I typically run either gunslinger or shadow stalker)
