The trash might be frustrating, but it won't be that bad when you know how to kill a boss and most likely 1-shot them every time you go to Karazhan, meaning you'll only have to kill the trash "belonging to that boss" once. Besides, like someone mentioned, the trash has a semi-decent amount/chance of dropping some patterns / epic gear and - up to a certain point - also provides rep. Yes, you might be halfway through revered already but had you been that had there been no rep awarding trash respawns that you'd had to (re)clear? And, the minute you have the strats down for the trash, it won't take you 30 mins to clear it. Another time saver is to cover everyone's role in a boss encounter before you start killing the trash. Now obviously this requires that you've already wiped on the boss a couple of times so you know his abilities (or that you've used a Strat guide / video / whatever - I hate them all). Having done that (covered everyone's role on beforehand that is), you can take a minute to pot/buff up and then get in more tries on the bosses.
Also recall that you can reset some of the Karazhan bosses, like for example Moroes. If your MT or someone equally important goes down, just run out. Sure, some will probably still die but eventually he'll reset and with any luck a healer has survived and can rezz.
Btw, "
rogues are pretty pointless, warriors have been nerfed to fuck"?
I beg to differ. We have two rogues on our somewhat irregular Karazhan Team setup (same deal; small guild, 12 attuned, we take what we have) and it's working out pretty well. Have them spam feint, and (if you have a paladin) throw BoS instead of BoM and they'll be fine. Or just be a little bit less trigger happy and stay alive
And warriors... they don't do enough dps or don't tank well enough? Warriors just got a giant buff in the last patch and as opposed to druids, the epic Karazhan/25man raid warrior gear drops will allow for some pretty decent boostage. Also recall a dps warrior in +def gear (making him uncrittable) can - if needed - (if so only for a while) fill a limited tanking role as OT.
Love you guys (but Vehas, he's just a dick
