Ok so little update:

- Vault of the Wardens +2 - finished 2 times - first time: 29:26, wiped on last boss twice if I remember correctly. second time: 26:35 ( missed 2 chest by 11 seconds )
- Darkheart Ticket +3 - finished with 2 chest reward with 22:06 time. Unlucky that I got +5 Halls of Valor key from it

Still have a Black Rock Hold +3 key from VotW run which I think I will be trying today or tomorrow, the only part I hate about this dungeon is the stairs where they throw rocks at you... grrrr

Have Neltharion's Lair +4 with Raging which I should be able to do, might need to use Potion of the Old War for Naraxas to burst him down.

Once I finish my Karazhan quest line I will go there as soon as possible
