I remember that time, when my FC first cleared T9, before jumping on the recently released T10, our MT wanted the HA coat of fending.
It took weeks before we ever got it, everything dropped for everyone's main and alt classes, everything but the HA coat.
When the HA coat finally dropped, we (happily) moved on T10.
Now, every time we bring a new person in T9, the HA coat drops together with the tears of the people that were present in that period of hell.
