You mean, on your way to Livid? Yes, of course, but I routinely use Charging Bull as a go-to skill for my 2H Warrior. Now I'm thinking I might want to respec.
Nope, devour is expensive to use so is wrath of heaven on a templar, charging bull lessens the pain a bit, knocks down enemies, generates guard and does decent damage. Im personally not a fan of livid as i run the war horn to panic, sunder, destroy guard and do damage in a 8m aoe. I make cass run horn of valour for guard generation, and for damage i prefer bloodstone as its always active and has a bigger range than livid (8 vs 5).
As a reaver damage is not a real issue, it is to ensure i get to do damage. I cant have enemies blocking or parrying my attacks and i cant be dying because i couldnt cast devour. Now regarding war horn atm im running the guard smasher horn, i will try the debuffing horn to see which gives me better mileage since switching between them is just a toggle, though im leaning towards guard smashing horn as it does 100% damage to everything so serves as a nice aoe damage ability,
