While I think 6 hour lockouts is ridiculous and really should be extended to at least 10 hours, my bigger problem with NTOV specifically is how you have to game the instance to get Vulak if ya cant do him in your 6 hour window. For instance, our current instance of ToV has all lords/ladies dead a spawned Thylex and no Vulak. The Instance should check if all Lords/Ladies are dead and spawn Vulak if Thylex is up, but it doesnt. So effectively you need to leave at least 1 Lord/Lady up if you don't think youll make your 6 hours so that when you go back you kill that 1 Lord/Lady and he spawns. Not a very elegant solution if you ask me, then again not much in EQ is.
