G’day legends, I’m Darkmech, a content creator for Method. I’ve played every tank at a top level over the years, in CE Raiding and High Mythic+.
A lot changed for Blood Death Knights in Dragonflight. The playstyle compared to the end of Shadowlands is completely different and focuses more on maintaining multiple buffs now and as always proper resource management. The playstyle is still relatively fast paced compared to previous iterations of Blood, and once again Blood is a very strong and viable choice for Mythic+ and Raiding content.
What has changed
Changes for Blood DK in Patch 10.2
In Patch 10.2, Blood Death Knights aren't seeing any changes outside rotational tierset interactions and even so these are passive, so you’ll still be playing under the same rule set you did in the previous patch of 10.1.7.
With the legendary axe in patch 10.2 being a strength weapon, BDK will no doubt move up the menu as a very solid raid and M+ Tank option and could likely get overvalued by the general playerbase as a result.
