Firstly, please wait for everyone to finish shrining and looting in pt2 before opening the portal and stepping in. To my understanding this starts the timer, and the shorter time makes it harder to deal with unusual situations, for example:
- Player "A" says "AFK" the moment he steps into the puzzle room
- Player DCs -> empty puzzle room
- Player has ragequit due to newbies killing nameds in pt2 -> empty puzzle room
- Player proceeds to run mindlessly over the 5x5 for 2 minutes before asking for help
- The only character with lock opening ability has trouble with lock DC
These all happened recently. I've recently been in multiple Shrouds where we've seen the wall and/or wiped before pt5. On normal. (Queue comment regarding common factor in failed attempts: me).
While you may be confident in your own abilities and most pugs breeze through the raid, there are times when we get a combination of players and characters that require more patience. I suspect we have the Stone of Experience to thank for this, at least partly, because I think it has become more common recently.
Secondly, and this applies to all level 16+ quests. Please bear with me, the Pessimistic Guy, if I ask everyone to wait or I'm talking through quest mechanics. I'm definitely not a super player and my characters are mediocre, but the knowledge I do have I try to impart to others.
I'm not dictating to you or talking down to you, Mr. Veteran *cough*I'll do what I want*cough*. I'm trying to get possible newer players on board and to finish the quest. I'm not that great at assessing individual players or the group as a whole, so as often as not my pessimism is unwarranted and we complete in record time. Nevertheless I'd rather look silly than die in the wall.
