I’m a bit behind in the times. My guild got their Rusted Proto-Drakes months ago, but because of my work schedule I haven’t been able to run 10 mans with the guild. But, thanks to the advent of the raid extension, we have been clearing most of Ulduar 10 on alts and leaving the last few bosses for mains to get their achievements. It has been a busy weekend so I am going to have to make this one short and sweet.
Predicative versus Reactive Movement –
Anyways, after having the pleasure of single tanking the Yogg-Saraon encounter last night in the ten man with only Thorim down, it got me to thinking about a lesser known mechanic that I use on phase three of Yogg to ensure that I don’t ever have to turn around and face Yogg. The trick involves the concept of the predictive vs. reactive mechanics of npcs. What I mean by this is that there are two different pathing methods that npcs use when reacting to your movement.
The first and most prevalent of these is called reactive movement. This means is that if you run into a mob and then back up to place him in the position that you would like him to stand, the mob will reactively move. He sees you move back and he counters moving forward, following you but stopping short in front of you. This is how most tanks move mobs, bosses, etc. They will run in, aggro the boss and back him up into place.
The second and less utilized method of movement has to do with predictive pathing. Specifically as you are moving, the mob will attempt to predict where you are going to move next and run to that position. This is very useful for the immortal guardians in the third phase of Yogg. If you properly employ the tactics that are necessary to create predictive movement, then you can effectively tank every guardian with out ever having to turn and face Yogg.
This is crucial because even with the best of execution, you will be running low on sanity when you enter the third phase. In order to get a mob to employ predictive pathing, you must strafe. Strafing enables the predictive movement of npcs in the game. All you have to do is stand about 20 yards away from Yogg, with your back to him, but your camera facing him, taunt a mob, and strafe up and left or up and right. The mob will run right past you and he will now be in front of you. This prevents you from taking a nice fat hit to the back and you don’t have to turn around to achieve it.
