Thanks guys!
Great tips.

So what you are suggesting is to Shield Lob all wolves so I have threat on them?
My common experience (regardless Low or High or Expert dungeon) is that most DPS will not wait for me to gain threat on every mobs with Shield Lob, as soon as I stop moving, they will nuke away.

What I mean by above statement is that... with GCD, after first Shield Lob my only option is to keep running forward and shield lob the the next mob, which in my case I always target the Goobue, then keep moving forward, and Shield Lob one of the Spriggan. This keep moving approach ensures that my DPS don't start nuking right away, a silent way of telling them that I'm still gathering mobs. However, this approach + GCD only allow to Shield Lob limited mobs, I do mix in Flash as I run past some of the mobs (it really depends on the position of the patrolling mobs), but what I'm trying to say is... Shield Lob every mobs may be difficult to achieve (Perhaps I haven't figure out the correct way to do so.) Anyway, after I have gather up all the mobs (exclude the wolves)I will go ahead and Flash -> CoS -> Flash -> Flash (at this point, I should be close to Half MP) -> Riot Blade Combo.

With above method, I think DPS usually follow me, since I kept on moving lol. Haven't experiencing the healer pulling mob off me with above approach yet. Perhaps he/she wasn't healing at that time, which worked for me.

Overall, I really do appreciate your replies! Just want to share my experience in some of the encounters with mobs and players. This is extremely helpful, it helps to see how other players handle each tank and their experience with it.

As for Warrior, in large pulls, keep spamming OP until out of TP and mix up with other skills to conserve TP. Would that approach work in all pulls? What if some mobs are not that far away, but just not part of the large pull, do Warriors usually have downtime to recover TP?

Thank You!
