Less so for the group build. But the solo build utilizes CoE and flame blades to give you doubled up swami stacks for both the fire and lightning coe.
Since you're using CoE you are required to have maximum cdr in order to reduce the archon cd short enough to sync up every fire coe (due to lack of obsidian).
@angryroleplayer for the build linked cdr is not near as relevant and you can get overlapping swami stacks easily for every fire with obsidian ring.
