There are a lot of things about Guild Wars 2 that I like, combat is not one of them.
When I engage with an enemy, I want to feel like I'm constantly inputting actions. With my 80 Engineer and 80 Revenant, I feel like I'm constantly auto attacking while waiting for the few situations where my other abilities are useful, such as AoE attacks, increased damage, ranged attack, etc.
Reading how much people enjoy this game, I have a feeling it's the professions that I'm playing that are the problem. Are there professions that have exciting rotations?
