Just a note:

Not losing threat after deaths in a party

Latency issue in team play

losing item if put in dark market or transmute and then canceling

Crashing issues while mapping or returning to town after a map (im not really sure how this crash is happening, its almost like the longer you stay in a game without leaving, the more memory it takes until it crash? i normally crash roughly 30-60 mins if i am a 3 map expedition. it also seems more incline to crash with spell casters or dots or builds that sees too many numbers appearing all at once, I notice my friend hardly crash running a bleeding edge build, it may be something with how spells can layer over each other too, im not too sure, just making some hypothesis.)
