Any role will have it's pros and cons to leading because of awareness and what their role involves.
Calling out things like tank swaps or repositioning of mobs is something best suited for a tank because they are the ones doing it and its their job naturally so they are more aware of it. For example, if traps are spawned in an inconvenient place to be used, a tank is the ideal one to call out if the entire raid should shift on the Shannox encounter in order to align them closer to the traps they intend to use (assuming using the trap Riplimb method of reseting debuff stacks).
Calling out things like raid wide cooldowns for damage mitigation and healing cooldowns is best suited to healers simply because they are the ones most closely monitoring the status of the raid and the rate at which damage is being taken. For example, a healer would likely be effective for calling out cooldown rotations on Beth'tilac phase two.
Calling out target swaps or a reallocation of damage is best done by a damage dealing class because they are directly concerned with not just dealing damage but how that damage is distributed. For example, a damage dealer would likely be effective for calling out steering shifts on Lord Rhyolith in phase one.
Naturally a raid leader isn't going to be aware of everything but with practice and understanding of the other roles they can become a little better at it. However never feel like you are required to do something simply because you are the leader. If someone else is better suited to the particular task, let them do it instead. I listed three examples where all three of the roles, based specifically on what they are doing they would be the ideal person to call out orders.
Don't be afraid to delegate. At the same time, if you can do better, don't be afraid to take charge either...
