Using Chrisfried's Nobel-deserving Guardian Theater, I finally got a full match of someone up against the PvE-centric Balls of Fire Titan build that I main in PvP now.
It's fun to see how a non-meta build causes the Shotgun-sliding sweats to slowly lose their sanity:

My build is not quite identical to Aztecross’ build, since I tweaked it for PvP purposes. If you want to try my variant out for yourself, here is the DIM link to save as a Loadout:

(Do note that shared loadouts occasionally remove your ornaments and shaders for some reason, so be sure to remember what your Guardian looks like before applying the loadout!
