It may be the case that you’re acting more reckless with more gear? With less gear I pulled much more carefully, used more of my toolkit like personals and CC and basically never died. Brann also never got a chance to pull anything because I pulled the mobs to corners that didn’t leave room for surprises or additional adds.
Now I die more frequently because I just pull, start blasting and don’t pay much attention anymore. It happens from time to time that a regular group of 3 mobs just kills me because I underestimate the incoming damage or fight to close to another trashpack and Brann adds something.
