Honestly Guardian Druid is the only tanking spec I would have said needed a similar amount of attention to fix the glaring issues with it overall.
Secondly in response to your comments about Season One Mythic Plus and Blood DK’s if you look at the history of the class and when they have been strongest in terms of tanking there is two very distinct aspects that are apparent
It’s usually only in Season 1 when the gearing is low for everyone but when you factor in scaling and the following Seasons majority of tanks surpass the Blood DK due to the classes crippled scaling in terms of gear that has been an issue since Cata.
It has been a case of one element being maybe a little over the top when comparing tanks examples Blood Shields, Healing, Bonestorm etc. However, instead of slightly modifying the one thing that is the issue they gut the ability and then add two to three additional layers of nerfs that just don’t make any sense and stunt the class so much.
So lets see you have Blood DK with the Lowest Overall Armor/Mitigation of all tanks including Guardian by a Significant margin. Mages and Warlocks have more Mitigation and Armor than a Blood DK for example which is ridiculous.
You have Blood DK’s doing the lowest DPS of all tanks in the game by a massive margin the gap between Blood DK and the next lowest tanking class is around 10 - 15K DPS on average which is significant and it’s almost 50 - 60K DPS to there top tanks.
Finally the thing that everyone seems to whinge about in terms of Blood DK’s - their healing. Well if you consider that currently a Blood DK can be doing 100 - 150K HPS and that’s isn’t even enough to keep them alive through the onslaught of damage. While a Monk or Warrior can be doing as much as 40K - 80K HPS while mitigating 70 - 90% of the incoming damage meaning they are pretty much self sufficient and require zero healing from a healer. However, with the DK the healer is constantly spamming to keep them alive.
All we are asking for is MITIGATION bring back the armor that was taken earlier in this expansion and increase the damage the class is doing to make it at least some semblance of competitive.
