FFXIV: BLU O12S Clear

The raid that struck fear in me back in 2019, as hard as many people said it was and as long as it took some groups to clear...I've finally cleared myself...synced, as Blue Mage!
At HW2 I was so zoned in topping everyone else off I mistakenly got clipped by another defamation xx
But a quick adjust and fast raises we still had the output to keep going.
Watching back the footage, I know how I can improve if we were to go back and do it again.
Any advice for other people learning; as the gobskin healer you won't benefit much during the Revenge Blast windows, so that should be swapped with Triple Trident. Depending on the groups damage, healers may not be stinging, so I could also probably have swapped Whistle with Glass Dance.
And the most important thing I think every o12s group struggles with. __DoT UPTIME__. Make sure to always have the DoT rolling!
