The previous response shows that you arent actually reading any of the viable feedback youve been given, so this reply isnt for you OP. Unsub, throw a fit, do whatever makes you the most/least miserable. To anyone else who might happen to see this thread and be in a similar situation, this response is for you.

As someone who played the game for more then 50 levels, you already know that quests dont take a significant amount of time. And even if one did happen to come up on the end of your current play-session, you could always leave it unfinished and come back to it the next time you play. So the quest series of these raids is a non-factor. As for the instances themselves, they are much shorter then you might believe. A normal dungeon is 3 bosses with some trash mobs in between, while an alliance raid is 4 bosses with a couple packs of trash to wipe out(usually 6 or 7 encounters total). A good group will finish a typical dungeon in a bit under 20 minutes. A run of the first alliance raid(LotA) is usually about 18 minutes. A run of the second alliance raid(Syrcus) is usually about 15 minutes. The last one(WoD) is a bit longer, and usually takes 25 or so minutes. And those are typical times, so a good group can beat each of those estimates by a few minutes(ive seen syrcus done in 11 and change). And remember, there are 2 roulettes(on top of anyone who skipped them now catching up and anyone running them for exp) that feed into these ques so they dont typically take long to fill. Because the group composition is 3 tanks, 6 heals, and 15 DPS this ends up a case where going as healer or dps is a little quicker then tank, but not by a crazy amount.
