But as it turns out, there's even more cool stuff hiding below the surface. If you're like me, chances are good you've spent a day or two chain-running heroics to gear up an alt or to get instant gratification on that badge item you want. The issue with chaining heroics at this point in time is that eventually you hit a wall: do instances you hate (Oculus) or stop running instances because of your 24-hour heroic lockouts.
Well, in patch 3.3, everything's a-changin'. While heroic lockouts aren't going away, they will not affect your random dungeon selections. What this means is that if you and four guildies do a timed Culling of Stratholme run, and then you join the queue for a random heroic, you may be assigned Culling of Stratholme a second -- or third, or fourth -- time, depending on your luck, as your random dungeon. And you'll get two extra Emblems of Triumph for completing the random dungeon each time, even if you've run the dungeon already that day. The only way that your lockout will affect you is that you cannot create a group with /invite for that same dungeon again that day.
Basically, as long as you're choosing the Random Dungeon option, you can run as many heroics as you want, every day.
With increased rewards for, easier access to, and the trivialization of lockouts for heroics, Patch 3.3 is the perfect time to dust off that neglected level 80 alt of yours and take him or her on a tour of Northrend's most dangerous places.
