Sometimes the problem isn't the tank. I've been in various dungeons where the Tank tries to mass pull but before he/she can even finish establishing his aggro the healer is already spam healing him, but yea as long as the tank and healer has an understanding on how their going to handle mobs and when to heal etc then it should be fine. When I had my previous toon which was a tank I dont do mass pull very often except when I was in Brayflox Hard and I tend to use Shield Lob then Flash, then moved on to the next pack and do the same but adding a 2nd flash then do my normal rotation while flashing every 2 rotations that I finish.
