Tier list!

Snip

When you make a tier list, you make it for a specific game mode, as class potential varies based on the nature of the game. For example, a WAR by far the best tank in Solo Queue while PLD exceeds it by leaps and bounds in premade. Most games have similar formats of separate tier lists.

Also, when I said "potential vs effectiveness" what I meant was that it seemed OP's list was developed with a one-sided match in mind, especially in the sleep department. In a perfect condition, a WHM would have to use FOUR GCDs to use up all of the enemy team's purifies. In a game where it is very possible to kill someone in 2-3 GCDs, sometimes even 1 GCD under certain conditions, those GCDs not being used for healing is extremely risky, and often detrimental. This was obviously not taken into account when OP made the list.
