I’m still a total newbie at GW2 (I just got my thief to level 18), but I tend to agree with the OP. For most fights I find myself running in circles and dying all the time. The fights go by so fast, I don’t know how to learn from my experiences. My wrists get tense and I get tired of combat very quickly. Even fighting single normal mobs is a touch and go situation. I’m not sure I have the nerves for this type of combat.
However, plenty of people like this game’s combat system as it is, so who am I to complain? GW2 ain’t the only game in town.
(My single-digit frame rates don’t help either!)
