Mesmer/Warrior

they don't get adrenaline do they?
since mes is my main i get energy instead right

Everyone gets adrenaline when they attack but only a warrio has skills that use it. So yes you gain adrenaline.

Energy and Adrenaline are different things. They do not replace eachother in certain professions. Every profession has energy, but only Warrior specific skills get adrenaline. Adrenaline is not in a "pool" like energy is. Each skill gets its own adrenaline to fill it up. So if you used a warrior skill that requires adrenaline, then it will get adrenaline as long as you are attacking.
