On shadow priest solo levelling, am I right in assuming in most regular player-to-mob situations two orbs (before DP) are more convenient than three? Please let me know if I miss something. Also, I'm a bit confused about 3 or 4 mobs AOE, because it's supposed to be the 2 dots and then regularly a management of orbs with DP and MF/SW:death but it appears to feel a bit slow.
