"Don't die git gud" is terrible advice, because it's perfectly normal to die to slip ups in quite a lot of content. It leads to players getting far more frustrated over deaths than they should be because they assume either they suck or they're not meant to die because the forums said so and therefore it needs nerfs. Dying is part of the learning experience and brain derps happens to literally everyone in all content so lets not ridicule people for it.

That said, this used to be an issue in previous patches, but Enix have done a lot to make it easier with base instinct, 100% chance synched and huge buffs in the chance to learn skills unsync. Your options are generally:

-Solo it with Base Instinct. Quite a fun challenge.
-Reach 70 and unsynch it. Might take a few tries but makes the majority of abilities very easy.
-Unsynch it with a group. Same as above and works for pretty much everything.
-Synch it with half BLU and half healers. Easily done for everyone in 2 runs.

So pick whichever works best for you depending on the content and there should be no problems.
