Well I've quested up to about 76.5 and I'm getting a bit tired of the collection quests. Which instances have the most trash mobs in them? I'm thinking I'm going to grind out a couple of levels before I go back to questing but I need at least 12 mins of condensed trash mobs to make it worth it. One of the nice things about wotlk is less trash mobs, unless you actually want to grind on them
