Adrenaline question...
30 in arms for Furious
or
30 in Discipline for burst mastery
For hammer its better to go for burst mastery because, well you dont hit that much so you benefit more.
If you run something like a longbow (auto attacks do 2x hits) furious is way better choice.
And yes to start a fight its always difficult without adrenaline, maby you can start with signet of fury.. but i think the signet itself sucks..
For hammer i would go for berserker stance.. you gain adrenaline very fast at the start + you cant get conditions for 8 seconds.. so you dont get blinded and your save to hit your Earthshaker :-) good luck!
hammer build would be 0/10/30/0/30
Harass enemies with a ranged weapon if they are out of hammer range. Staying in combat keeps your adrenaline up even if slowly with Signet of Rage.
The rest is merely getting as many hits as possible to keep it full.
If you are a Signet warrior, the Fury one will give you a full bar immediately upon activation.
There’s a number of ways to get it up quick, but lack of combat will always cause it to empty quickly.
The more pro warriors here could likely enlighten you a bit more.
There’s also Cleansing Ire when generates adrenaline when you’re hit. I run 0/10/30/0/30 Hammer + Sw/Sh with both Cleansing Ire and Burst Mastery. As long as I’m in combat I don’t usually have adrenaline problems. I used to run Healing Surge and Signet of Fury, but found I didn’t need them to keep my adrenaline up. Swapping to your off-set when Hammer stuff is on CD will also generate some adrenaline.
