Not on Tanks those are generally done by DPS players who do full blown out guides and breakdowns
generally because the house rotations and different play styles that are not unique to tanking

Tanking doesn't really require a ''guide'' as our rotations (even optimized) are pretty clear cut

Tanking is more skill and ''knowing'' rather than being guided. I dunno me reading a PLD ''guide'' really couldn't help me
v.s just learning encounters and what cool downs to pop at the right time etc.

I can say this though

-Learn the best time to use CDs (Not just because they're up)
