FREE TIP : Divide the room into sections like this.
the brown square is the platform ranged stand on during the first part, melee follow boss.
those are the 4 sections, in normal mode you run the each section and stop for about 1 second then keep moving. this is assuming you dont have movement enchant lol
in heroic mode from the first section you KEEP MOVING and dont stop. left to right. pause for 1 second at the end, turn around and run all the way back.
most people didnt really understand it until i drew it out for them :P you guys should go for the achievement! [The Safety Dance]!
GL and have fun with WoW DDR lol
