Really, though, just work on whatever ranked goals and get sockets on the way. You can reduce honor costs by buying the 3 bloodstones required with gold.
Don’t even bother with them for now, outside of your meta gem (and one additional colored gem if you’re using Focusing Lens embellish).
The season is ending in a month. Next season is using the exact same bloodstone currency for new sockets. Just hold on to them. They amount to very minimal secondary stat gain which isn’t worthwhile for such short-term use.
