Incredibly Annoying Black Mage Issue Regarding Thundercloud

[randysquirrel]

You have to make a decision as to which one to use

That decision is "Do I use the proc that hits for 510 potency, or the proc that hits for 710 potency?"
There is literally never any time it would be a benefit to using the lesser proc. It's not as if they do different things and there is a decision process where you must decide which one fits the situation better, they literally do the same thing, except one hits harder and lasts longer

it's proccing near mid button press and is being wasted on a skill you meant to cast normally. ._.

That decision is "Do I use the proc that hits for 510 potency, or the proc that hits for 710 potency?"
There is literally never any time it would be a benefit to using the lesser proc.

The problem here wasn't choosing the wrong ability, but choosing any ability too early. If there was time for it to proc before initiating the weaker spell, there was time to wait to see if it would proc before choosing which spell to cast.

We're BLMs. We know that RNGebus is a cruel master, and that he may spite us at any moment. If there isn't already a Thundercloud proc in advance of Thunder 1 time, then play Chicken with the Thunder 1 button. Press it at the last possible instant that lets you start casting without delaying your GCD.
