The Spirit Realm

Through the 13th anniversary tasks, I picked up a couple new items and request suggestions on the focus:

Through the Rumor task, I picked up the ring of the ancients (wrist).

I currently am wearing a lucid wrist (disease) and nighthowl's bracers (poison focus). The ring of the ancients has poison damage focus. Inspecting stats, etc, says I should wear nighthowl's and ring of the ancients, but then I would lose disease focus. How much weight should I put on the disease focus?

Through the ToFS mission, I picked up the crystallized shadow ring (bene MP).

I am currently wearing gripworn steel band (bene range) and energized feedback loop (bene MP). Inspecting stats, etc, says I should wear the energized feedback loop and the crystallized shadow ring. But, then I lose bene range focus. This is less concerning to me as I rarely have issues with range with my play style. How much weight should I put on bene range? I mainly solo or small groups and never raid.

Since the one of the new fast dots is disease based, having the focus is more important than in years past. I would get it if you dot much.

I don't think bene range is as important for a soloer/grouper as it would for a raider as people just don't get as spread out in the group game.
