Cure v. Cure 2

[Silver-Strider]

The two stupidest things WHM's do:

1) Using Medica II on trash
2) Using Medica II before the party takes damage

Those not only waste MP, but they screw up the Tank's ability to hold hate.

If the tank is having a hard time holding hate, that indicates a few things.
1) He/She over pulled more than they can handle
2) He/She is inexperienced at tanking (Shouldn't happen in later dungeons, but jump pots are a thing so not entirely impossible either)
3) Tank is out of resources to hold aggro. Usually a WAR problem but I've seen bad DRK have a similar problem as well.

As for the Medica 2 before party takes damage, it's mostly for preventative purposes. Take Lakshmi ex, for example. Usually, the Hand of Beauty > Stroham combo can result in DPS dying so the regen between Hand of Beauty and Strolhim casts helps immensely, especially if you don't have any shields for whatever reason (I blame all you AST that insist on using Diurnal vs Noct Sect when paired with a WHM)

.The next stupid thing that specifically WHM's do is spam holy. Don't do this. Cast Holy, cast something else while they're stunned, either heal or cast Aero III, then cast Holy again to maximize the stun time. If you can wipe out trash before the stuns wear off, that saves you a lot more healing effort than back-to-back holy.

This seems counter productive. If the Trash dies before the stuns wear off, both Aero III and the heal are useless because
1) The DoT from Aero 3 is mostly wasted and the flat damage from Holy will trump the little damage that Aero 3 would have done in the same time.
2) There's nothing left to do damage so why waste the MP to Heal, especially since WHM has several oGCD they can weave between Holy that don't need to waste the GCD on a heal.
