[quote]it's arguably the only useful gunslinger exotic for pvp[/quote] Boom, there's your reason. They're trying to not create a "one Exotic rules all" scenario which kills diversity. Achlyophage was pretty much the only Gunslinger Exotic you saw back in Year 1 used, just like how The Ram became the one to rule all when House of Wolves was released..Now that they're both nerfed other Exotics get their time in the sun. Gotta accept the fact that Symbiote is more of a PvE Exotic now and is no longer the easy mode PvP one.
