Making as many posts until this is fixed ASAP. Blood shield not working for Characters boosted to 80 in store

I have been reading online and this bug has apparnetly been around FOR MONTHS and blizzard hasnt done anything. i dont know if this is for other classes, or only if u bought the 80 option in blizzard store. Blood shield in cataclysm classic or possibly just mastery stat in general. ISNT WORKING properly. if u select the blood talents improved death strike which increases ur death strike heal isnt increasing ur blood shield at all. BLizzard u need to fix this asap. as this is nerfing there survability into the ground for people who are doing more challenging raids like with less people or for solos or videos. PLEASE PLEASE Fix this now. i have a video i can link of me recreating it.

example so if you take 3/3 in imrpoved death strike its supposed to increase the amount healed to increase ur blood shield and it dosnt. u can pick one point in blood talent and u will get a shield then take the poiints into improved death strike and the shield is exactly the same. if not even lower then it should be by a MASSIVE margine.

i know the class is OP and hated i get it, but this still needs to be fixed asap as this is stopping people from doing things they could do in OG cata.
