Armamentarium works for Defender too, I always tend to use that because of 2 suppressor grenades(When I play defender). My bubble seems to get shattered or no one walks in it at all. What they lack in PvP exotics, they more than make up for in PvE exotics, Saint-14, Ruin Wings(Possibly the best PvE exotic there is), Peregrine Greaves(With arc burn + brawler it's insane, or even just one of the two). They are also a must for some things, or were before everything got outdated, like Crota. I agree they could use more PvP exotics, but you can't compare anything to the Ram in pvp, it may be the best PvP exotic there is, and a nerf will surely come for it. But I was mostly stating the class itself, overall, it isn't as bad as people make it out to be. Other than t-rex arms lol
