Not yet - my game time is somewhat fragmented across platforms, and this specific Zane is on Xbox, while Torgue Moze/Pistol Zane are on PC/Epic. I also frequently don’t pay attention to these subtle (and sometimes not so subtle) interactions.
Also - not sure why, but relics is something I pay the least amount of attention to.
Edit: Pistol Zane went to the first map of DLC1 and promptly ran out of ammo . Had to alternate between MNTIS and Clone deployment, but then also realized that Hanging Chad still had couple of rounds left in it, and, well, since it does not consume ammo… Was able to chisel away few enemies to get out of this tight spot.
Need to look for on-level Chad in Earl’s machine now, just to have one as a last resort back up.
