We ran Karazhan the other day and for the first time in a long time we didn't clear it in one run and took almost four hours only to call it at Prince. Only about half of our regular group could make it that day and we were forced to PuG the rest, even filling the last spot with a player who had never done Karazhan before. Our raid leader and tank grumbled throughout the entire run, sending me tells of wanting to kick people from the group. In the end, we conspired to end our misery by acceding to a couple of attempts at Prince but no more.
For the past weeks, we had been doing 2 1/2 hour Karazhan for badges, and for the most part we made sure that our raid members were equipped in Tier 4-5 or better. We'd turbo pull to bosses with a Paladin tank and Disenchanted nearly every drop because, really, no one needed anything from there. We ran it for badges and wanted to breeze through the instance as quickly as possible. We would wince if we brought someone who wasn't familiar with the strats or had more than a few blues.
