Some MNK advice needed

[Lilyth]

Hello there!

Ideally you want to use your OGCDs as soon as they are available in order to maximize dps, however, you also don't wanna use them without being fully buffed first. In the end it really comes down to the situation that you are in. If it's gonna take too long to get buffed (no GL) and the boss is gonna jump soon, then go ahead and burn those CDs. If you already have GL2, perhaps it's better to use B4B and Internal Release in your GL2 rotation and then burn the other CDs once GL3 is up.

If the boss jumps you should always prioritize Form Shift. The main reason is that you don't wanna lose your GL3, ever, and form shifting helps tremendously with that. If losing GL3 is unavoidable due to mechanics, proceed to use TK and then form shift/meditate, just making sure you'll be on Coeurl form once the boss returns. If it's just a quick AoE dodge and you know the boss will be there for you to safely refresh your GL3, then go ahead and meditate.

Regarding TK, unfortunately that's really hard to tell. The only thing I can say is that if you are uncertain whether you should use it or not, then don't. It's best then using it too soon and losing your GL3.

Lastly, I wouldn't say losing GL3 is absolutely GG if there are no tight DPS checks like in Alexander Savage. But yes, it's a huge DPS loss.
