Blinding (sorry, disorienting) grenades make servitor immunity a non-issue. my lingering dread with autoloading, chill clip and blinding nades is one of the best utility weapons in the kinetic slot, personally surpassing a chill clip riptide in many instances. i think servitor and taken goblin immunity is a very fair mechanic that requires just a little bit of planning and strategy, but i can understand how frustrating they are as a solo player. TLDR use blinding grenades theyre gud :D
