Hi! How can i improve my TS Deadeye? I have invested about 10 div into my build. The clear is really nice, however i lack single target. I see people get millions of DPS on the same budget as me, meanwhile my PoB shows about 200k dps (Is it true or am I missing something?)

Right now i have 10div in my stash. Should I invest it now, or try to get like 30+ div to respec into omniscience?
