Hi,
in the current state of the tanks, the knight tank is by far outplaying every other tank.
Don't get me wrong, I like the fact/idea, that the Knight class itself should be the best tank, because it is a pure tank class in general.
But in the current state of "Threaten" and "Traces of the Cross Sword", the gap is really huge. Therefor I still suggest a second Orkham plate glove with a Threaten effect. (maybe only 75% of the strength?).
Furthermore I suggest for the Champ/Knight:
Change skill ID 1490549 that it will change "Rune Overload" to cost mana instead of rage per second and add a stamina multiplier on the dmg of 0.5 - 1.
Greetings
