For me, it still all smacks of breaking something that didn't need fixing in the first place.
I liked the idea that aggro was this vague, mysterious entity, that had no numbers associated with it. If I wanted to it to be easy for me to know if I can hold aggro against a hunter, I'd have played a game which had aggro and dps meters.
I fear that the future of aggro balancing will simply be to ask that champ or hunter what their melee offence is, divide it by 3 and then check my own melee offence. As long as my figure is higher, I'll be fine and there's nothing to worry about. I accept that it may not play out like that, but that's the way the changes read a present.
I really don't like the idea of having the javelin to use for range aggro. The foundation of the warden class is that flow/fluidity you get from gambits/masteries. Less panic reactional tanking, more about building things in advance in readiness.
Aggression was a great skill. If a few mobs peeled off you, as long as you still had one in melee you could bring them back.
