i was on Underbog Heroic today and i was farming chests with 2 accounts , 2 rogues.after ~15 mins (5th reset) it said we were not able to enter cuz of " we have zone too many times" etc.. OK so having nothing better to do (well ofc i had but i was boring) i was jumping in and out of portal till i zone in after the 1 hour "instance" (?) CD.
Then sometiems i was getting DC on both accounts and when i Entered world again i zoned back in instance.
i fortunately zoned back in UB 3 times more than usual (7 resets total) in 26 minutes.
im not sure if this bug works or how it is working 100% because i did the same "jumps-to-DC" on 6th zone-in attempt but it didnt worked .i had to test it 4-5 times
Post ur comments pl0x
my english kinda sux .if u want further explanation just ask for it.
P.S : i also want to say that im getting DC on portal jump after 2.3 patch.
Edited:
Dont +rep if it's not working.
