I lost track when farming BSW but I think I ran CoA 50 times a day. If ur asking how many different dungeons I ran in a day that would be all of them 1 and 2 to get undaunted lvled up on a new character.
10 or more in a single day. Never really kept count, but yesterday alone I ran 7, including all dlc dungeons and I know it wasn't the most I've done in a day before. I play healer so group finder times are pretty much instant if I'm not running with buddies.
