Some thoughts about the Knight class these days...
I was playing the warden and warlock tank these days, sometimes even warrior. So now I went back to Knight once again, in order to compare the K/X classes to the others. I have no idea what happened over the last patches, but I had really huge issues to hold aggro in trash phases against mage classes. In the past that was working much better - maybe it's because I'm not that much into knight these days than before, but it felt like not that fluent as I remembered from 2-3 months ago.
Also if it comes to support of the raid, I personally don't feel the knight anymore. Utility like Crowd Control is much more important and only Knight/Champ can handle that on an equal way. K/M is entirely useless, since W/P overwrites its debuff. Most other tanks are either selfish (which makes them also useless in my eyes, bcz tanking basically is just easy) or are worse than other classes. Before you take a Knight/Scout with you, you can rely on a Champ/Priest, which is way more useful for kind of the same utility.
In terms of damage sustain, the class in general needs to work more for the same damage mitigation, compared to warden tanks. Warden just summons an immortal pet that makes him parry every hit received. Resulting in the missing necessity of a lot of def, like champ or knight needs, since you can't parry 100% of your input. With only 2.5-3kk pdef you're good to go as a warden. Also damage mitigation of knights is quite worse since the adaption patch of mitigation formular.
So in my eyes, it's not at all necessary to play a knight if you want to tank these days. It's way more useful for the raid to have either a warden, a warrior, a champ or even a warlock tank. Knight needs much more support, more utility and more aggro, especially in AoE, which is much worse than any other tank out there. If a dps has forgotten to remove its hatred rune, a warden can still hold aggro against it, but a knight has lesser chance. I mean, it's still possible, but not with such a low effort. If nothing changes for knights, I will probably keep playing warden and warlock tank, which are much more useful in our runs, but is kinda unfortunate, because I really like the knight class. UwU
