I run DRK and I generally take my time with 1 small pull at a time but I generally get paired with DPS that can't seem to get that hint and try pull fishing for more mobs for to get aggro which puts more stress on healer and go off attacking trash mobs that I am not attacking putting EVEN MORE STRESS ON HEALER!!! I also make sure everyone is topped off on HP/MP for next pull but there are those DPS that just don't care about others which is why the only "friends" they have are people who just like them... There was a time were chewed out the DPS for going ahead of me and told them that if they kept it up I would turn off Grit and let them tank...
