Major Issue with Tanks!

I’ve been a long time player of WoW. I’ve always mained a tank playing at high end levels of mythic +. There is a major issue with how Blizzard has tuned tanks in Shadowlands season 3 and 4. The only viable tank now is Blood Dk’s. They are so overtuned that other tanks won’t even get invited to keys, or are being kicked out of keys for Blood DK’s. This is a huge issue that needs to be addressed ASAP by blizzard. The tanks are all in a good spot, except Blood DK’s are so over powered with insanely high dps and hps no other tank is even viable at this point. Blood NEEDS to be nerfed!
