I would like to share a story, then quantify which chains that, unless you are willing to start over, you will NEVER fill up a group for.
Last night, join a Co6 Elite run. The leader was a rogue/ arti/ ranger splash, so I figured traps were covered. I get in, tell him I will buff and head to the caves, and he reiterates it's just Co6. D'oh! I had spaced that. Couple other people had as well, as they piped up at that point saying no one had flagged for it. Leader is annoyed, which I understand, and we go in and do the Sorrowdusk part.
It's going really well, TBH, sub 4 minute runs on everything, Get to Co6, go through the first 2 there, even though he said something about how he hadn't planned on running the other chain and how he didn't like us infringing on his time I figure 12 extra minutes to get people flagged can't impact his playtime too much... get to the big temple and he ragequits. In the middle of everything. Just leaves. As you all know, this was right before the one with all the mephits and fire traps. On elite. and the highest level amongst us was 9, the sorc I think. We had a couple toons with sub-100 HP.
Long story slightly shorter, we finish, out of a full group at the beginning just me and the sorc at the end, but it got me to thinking. What quest chains do you run that you know the only chance of getting a group together is to restart? Off the top of my head I am thinking:
Catacombs
Tangleroot
Sorrowdusk/ Co6
I can't think of any others. Even like Delera's has good enough XP you can jump in at any time and run them, and the necro ones and VON and all that are non-sequential... Did this guy getting annoyed and ragequitting for us wasting 12 minutes of his time have merit? I know he had Co6 in the LFM and me and 3 others ignored this, but was I in the wrong or was he?
EDIT: ROFL, Wrong area to post this. I am too lazy to move it though.
