That's been the formula for a long time now. Shiny new toy to go earn every so often, when the majority finally have it they nerf it and bring out new toys. It started with Gjallarhorn. It was perfectly fine being OP, the elitist "must have Ghorn" posts were just fine and dandy. Then over 50% had it and they were using it to blast apart the Prison of Elders bosses to the point that mechanics were circumvented. Then it was nerfed. They had videos of Atheon being demolished in October 2014, they knew how OP Gjallarhorn was. But they waited over a year to let it be the carrot on the stick. They've been doing it for years now.
yeah but ghorn wasnt completely demolished and still was a pretty good gun.
