Please work on reducing the loading times when playing in a party, such as when entering another zone or respawning on an ongoing bossfight. The difference between solo (on or offline) and party loading times is egregious. It almost takes the fun of partying away. Often it’s even faster for one of the party members to enter a new zone and the others to port to them.
In case it helps, you spend a lot of time waiting for the actual loading screen to pop up, during which you can actually fight monsters. The loading screen time itself is long as well but not as long as the time spent waiting for it
