Personally I hate signing up for a random and getting every single heroic besides Forge of Souls, Pit of Saron, Halls of Reflection, or Trial of the Champion.
So when I do the old dungeons I like to spice it up a bit.
For instance in Halls of Stone (which has to be one of the worst in my opinion), on the way to Krystallus after the first two packs of adds. Casting at the boss from down below causes him to come fight where you are. He also comes with every single add that is in that area. Its pretty entertaining.
But my question is to you guys, do you ever do anything like that to make the random queue just a bit better?
Give me your input
