Hey folks. Friendly neighbourhood tech support MVP here.
Just a note here - going forward only Direct X 11 and Direct X 12 are being supported by Blizzard. All code dealing with Direct X 9 and Direct X 10 is being stripped.
This means that if the highest Direct X your card can run is 10 you will not be able to run Battle for Azeroth. Nope no "will run but will run at about the speed of mollusc dipped in quick hardened cement sinking in quicksand". Will not run. Full stop.
I can see this causing an issue with Wine users as (at least how I understand it) their Direct X 11 implementation is spotty at best.
Here are the Battle for Azeroth system requirements -
