Went out of town to celebrate the 30th birthday of a friend. Was a great night with lots of guests and drinks and foods.
Tried to get the Crumbling Hall step from this [cuss]
. Already have the other step and finally the right quest was up. Did it together with two guildies. When I turned the quest in I had checked the "What happened to me" tab of the combat log multiple times as well as being really careful when doing the whole thing. I'm 100% sure I did not get any damage from any source between accepting the Quest and finishing it. Didn't get the achivement though and, as expected, didn't get any help from the Customer Service.
If this was an ordinary achievement I would've just shrugged it off and not opened a ticket. But this quest is only available once in a blue moon, you have to complete almost ALL Golden Lotus dailies on any given day to even know if it is up and then the quest itself is so F'ING annoying! At least when you can't take damage from anything. Whoever came up with this is an incredibly horrible game designer and also a bad person.
Did a bit of Pet PvPing and although the system is much improved with 5.3, many battles still do not get decided by tactics or team setup but by luck.
