I'd just like to chip in some tips, I like the idea of taking Barreling Attack out of Rage and giving it to the Wars, I might use it on a War, never on my Rages- there's too many activateds in Rage tree for me to want BA. Albeit I wouldn't think Iron Jaw would be particularly useful for the Rage tree, it'd be a one-sided tradeoff for me, I wouldn't use Barreling Attack on my Ragers, and Iron Jaw would be very situational and I'd likely go for the other passive options.
I would love to see more activated offense skills in the War tier, when I think War I don't just see a heavily armoured tank, I see a master of weaponry, a skilled warrior, surely such a WARrior would have powerful offensive capabilities? (without having to hybrid into Rage and Theatrics to get said offense).
Not bashing War, I've had 4 fairly successful Wars and my next HoL will likely be a War (unless Shadow & Myst comes out soon, in which case I may change my mind) I just want to offer some little suggestions to help balance it out and not be so extremely pure defense (even Rage, which is supposed to be bare-all offense has defensive points in their tree (Ex. "Armour Movement", "Adrenaline Rush", "Heavy Scarring", and "Hard to Hit" whereas Theatrics has defense and offense in balance). War has pitiful offense, the only remotely offensively-driven skill in the whole tree is "Death From Above", I guess I'd just like to see less War-Rage offense hybrids and more Offensive-Wars, without having to rely on other trees to get its offense, it's a WAR-rior.
