Your threat generators are your war-cry line, specifically surety of death. You need to trait for light type damage in red, and blue.
Then wardens are the strongest threat generators without using force taunts.
This is exactly what I was mentioning; generating threat by doing damage. The war-cry line is light damage and has a damage over time component. For a tank to be generating threat by doing damage, is always falling behind to the DPS classes. This never was corrected for warden tank like it was for guardian tank.
Also regarding threat transfers, this is now how Defiant Challenge (and forced taunts) in general work. It takes everyone’s threat and Copy’s it to yours. Do that one time and you won’t lose aggro for a good minute. As long as they have generated threat first. You also have warning shot as a single target “threat copy” with a javelin.
Call me an old-fashioned tank, but if you need forced taunts to be tanking ok-ish, there is something very, very wrong. Forced taunts are "oh ####" skills (yes it is a four letter word, but it starts with a 'c'). They should be available in an emergency, not being worked into any rotation in any form. With it, they copy threat, they do not transfer it from the rest of the group onto the warden. Since my threat transfers are gone and I have no threat generators to speak of, I will always fall behind. They entire point of the threat generators from the other tanking classes is to stay ahead of your DPS and healer.
I will check out your channel and I sincerely thank you for your advice, but you also just prooved the entire point of warden being a poor tank and deservant of developer love after all these years. I shouldn't need to work my forced taunts into any form of a rotation. I should be looking at my most threat generating gambits and execute those to keep the mobs on me. I should also worry about building some defenses and maybe some self-healing (which also should generate threat). And if I loose aggro to my healer, then, and only then, I should use a forced taunt. Otherwise, I need to be able to rely on my threat generating skill/gambits that are not forced taunts; like with every other tanking class in every other game.
