Q: Do you plan to bring other tanks to the same level as Death Knights who have a lot of advantages over other tanking classes (easier to heal, quite a number of various safe abilities, etc.)? - 
?? (EU-RU)A: Death knights are a somewhat different style of tank compared to the others. They take significantly more damage than other tanks, but then heal/shield that extra damage back instead (and sometimes more). Due to taking more damage, and that damage coming in spikes, they’re also the most likely to die to unexpected burst (such as when they don’t have runes up to Death Strike, have no cooldowns available, and fail to dodge or parry a few attacks in a row. They also have more personal impact on their own survivability and mitigation than any other tank, by tying much of their performance to Death Strike (and especially optimally timing their Death Strikes). So in the hands of a really skilled player, they can do some amazing things, but not usually much better than the other tanks. We’d actually like to head more in that direction with the other tanks (making them tie more of their defensive performance to their ability usage), in the future.Uh.................. /flex?
Or maybe the dk just has a shit rotation.
