First of all, shoutout to sVr for showcasing the viability of Reaver + Chantodo with no set bonus for possible early season option.

My main idea with this was to leverage the power of the newly buffed craftable sets with the new Reaver + Chantodo.
Priority at level 70 would be complete a bounty set for Crimson plans, craft Crimson set, upgrade rare for Chantodo set and Reaver, and possibly farm a few bounties for RorG.
Optimally, blood shards from your challenge rift will be used to get a Swami from Kadala at level 30, and a Fazula at level 33 if you are lucky.
After that, you simply transition into Vyr 4 piece, and then 6 piece as quickly as possible.
