Once human out of content?

I have played about 100+ hrs and i have about everything. A full shelterer set + the guns and mods. Kinda full burn build. I feel that my items and set have no purpose now, i have beaten every boss on every difficulty. I have completed all Silos and i have about enough deviations. So what's the point anymore? I'm mostly offline now as there is nothing more to do. Even the recent 5GB update had nothing to show. What do you guys think about this issue?
