No, not the game silly!
After how many wipes do you say this group/raid just isn't going to cut it?
I don't have a magic number, just a feeling. I don't have unlimited time (who does?) and wiping over and over isn't always productive.
My old raid leader seemed to function on zero sleep. His motto seemed to be keep wiping until the thing is dead or 'fan;gwrwgfmcwkc;wowieon' appeared in raid chat due to people's heads falling asleep on their keyboards. (Did I mention I don't miss that part of raiding?)
Back when I first started WoW (had to be on the weekends!) I remember spending over 3-4 hours in a lowbie instances. I'm not talking Molten Core, I'm talking places like Maraudon and Sunken Temple. Not only were the places prone to lots of wipes, the corpse were runs brutal and the instances themselves were huge!
People seemed used to spending hours upon hours upon hours doing single instances. I'm so glad TBC made them shorter.
I've been pugging them all so far, with one or two friends joining me every now and then. But I have only bailed on one. I chalked it up to my inexperience. After wiping on the same trash for about the fourth time, I felt I wasn't up to the task of tanking. And I definitely wasn't up to doing it over and over. I apologized to the group and they removed me.
Later I did the same instance with a higher level of players, great cc and we finished it in a decent amount of time. No muss no fuss.
