I'm pretty sure the nerf to caution has affected Barbarians more than it has Knights. For a Barbarian, there is no other general purpose defensive spell. NGD nerfed the wrong thing.
To make it worse, we're not as effective an offensive force anymore. It's not down to tactics, we're just not, plain and simple.

lol to this, barbarians are an excellent offensive force, they have more areas than ever.

Try out frenzy if you want

Wait...did Barbarians even GET nerfed, other then the caution thing?

Yes, and quite possibly we got hit by the nerf hammer most of all, especially wrt. damage dealing capabilities. Weapon buffs are now cancelled when you switch weapon, rendering the 3 weapon magnifications completely useless for all but the most simple minded of barbarians, OWTH no longer applies to the caster, meaning another -15% dmg unless you are more than 1 barbarian in the group.
As to setup-specific skills, the highest damage spell South Cross got its potentional damage drastically cut. Thunder Strike (and the other weapontree areas) got nerfed, people with it in their setup either have an useless area or have to find 4 skillpoints from elsewhere...

Defensively, Caution nerf as well as duration != cooldown on both Caution and Frenzy means that we are quite a bit more fragile aswell.

You forgot to add that weapon magnifications now add 75 damage instead of the 50 it was before and that is was announced long ago that they weren't supposed to work together. If you put points in your area it will be as good as it once was. Most classes need to put points in spells to get it any good. Furthermore, if you search the forum I am sure you will find a lot of reasons why South Cross got changed in a normal spell. Also, barbarians got two very nice areas now in two mastery.

Honnestly for my barbarian the nerf wasn't that hard to overcome, however yes we are weaker but my barb was quite a tank previously. Really people should give a try now to the 2 handed mastery tree.

I don't contest any of the above, I was merely challenging the notion that barbarians somehow got "away" with this update, which is clearly not the case. For the most part i'm positive to the balance changes, with the possible exception of weapon magnifications, rather than rendering them useless as has been done now (the change of +50 to +75 wasn't "forgotten", merely irrelevant), I would like to rather see them cancel out each other when one was applied over another. This would accomplish the same end (not being able to stack them) but at the same time not penalize warriors utilizing more than 1 weapon tree (which counts for about 99% of the decent warriors I know).

Screen from today. Slashing arrows, slashing rings, bow with dmg bonus and dext bonus, medium 20m lvl 50. This barb had no caution. He had full hp and killed some leveling lock. You call this fragile?

The dmg bonus for each weapon wasnt 50 to 75, it was +50%(yes there was a percent sign there) to +75

my only issue with this update is that every class sememd to get nerfed, except knights, which are blocking everything now, yesterday i witness and lvl 39 knight beat a lvl 49 barbarian, after the knight blocked 6 of his attacks... tell me if thats right?
