so they say:
Cataclysm
April 9, 2017
Over the past 2 months we have updated over 300 fixes to Cataclysm. With our main focus being on spell and combat reports, we managed to resolve 150 issues in that area. At the same time, we have worked on general creature and loot issues in all of Azeroth. At the moment we are almost out of confirmed spells and combat issues, and thus are focusing on other areas.
anyone knows/found out what did they fixed actually?
