I'm only level 44 so I don't have the second AoE taunt. I like to spam Threatening Shout constantly since it's such a short cool down anyways. I'd rather use it when I am able to than when I need to because chances are I'll be in some other attack or skill animation when I need to use it, which means a second or two for my healer to get killed.
It's also not that I only use Shouts. I do attack during cool downs. Against something like CR boss, I will Shout, block, do some damage skills and debilitate, block, Shout, repeat.
I do understand where youre coming from, but I still think it is wiser to not use the shouts on cd.
When you are in a different attack/skill animation while you loose aggro just block for a moment, canceling the animation and then use the shout instantly.
(doesnt work the other way around since you cant cancel the shouts to block cc or whatever)
You could also use shield bash or 2xleash to get aggro back or at least enough time to use a shout (and time for your heal/sorc to get out of the way).
Using the shouts on cd could, for example, get your sorc killed if he is asking for it and is going all out right after you used a shout (in my experience there is no way to hold aggro when a lvl60 sorc goes all out and you dont have your shouts ready) of corse its his own fault then, but still, people tend to make mistakes or just do stupid stuf
My general "rotation" against bosses would be something like:
Start: Challenging Shout - Stand Fast - Riposte - (only now my teammates start hitting him)
Fight: Shield Bash (on cd) - Onslaught - Shield Wallop x2 - Spring Attack
In between some "Combo Attack"s when we dont have a mystik and I need to replenish mana and "Debilitate" before the 3 stacks run out.
Of course this beeing tera it doesnt always work quite like that, but its what I try to do so to speak.
When I loose aggro (happens very rarely, since the healer does not need to heal very much if I and the team no not mess up and when the sorc nows how to hold back and not waste all his mana in 1s) I use shout or cc if necessary and the cd allows for it.
Im not saying your way of doing it is wrong or something just that I think I can do more damage, block and cc when Im not using shout when it is not necessary.
