Levelling an alt. Using XP scrolls and doing the dolmen grind in Alik'r. Every single loading screen we've gone through since the grind started has been a "this may be an unusually long load time" loading screen. Each time I use the wayshrine, I'm stuck on the loading screen for about 3-5 minutes. By the time I successfully load in, the dolmen has already been destroyed by the rest of the zerg and I have to port to the next one...which results in the exact same thing occurring.
The XP bonus timer continues to tick down while I'm in the loading screen, so this results in most of it being completely wasted sitting on my ass doing nothing.
The only way I'm getting anything out of this grind at all is deliberately porting two dolmens ahead each time, so that by the time the incredibly long loading is done, the next dolmen is about to start.
I haven't been recalling, just using the wayshrines thus far. My friend, who is in exactly the same boat, claims that by travelling to a player in the group that's at the relevant dolmen, the load time will be as normal. I've just tried it, it works. That said, the load times are still incredibly slow when I teleport by going to the wayshrines.
