Dropping Grit

[Thoro39]

^Terrible advice. The increased MP from Grit Syphon strike is a moot point, when Bloodweapon gains you so much more MP, Bloodgeneration + Attackspeed while having no Grit penalty.

On dropping Grit, watch how the damage goes. General rule is, if a boss is busy casting mechanics, he wont autoattack you, meaning you're taking little to no damage, which makes your grit migitation useless.
Your Grit migitation is also less relevant in raidaoe phases.
If everyone is taking 10k raidaoe damage and you reduce it to 8k raidaoe damage thanks to tankstance ONLY on yourself on top of having a personal healer-regen, that 2k extra migitation thanks to grit was also useless, as the healers still have to use aoe healing speals that heal for 10k HP for everyone else, which will hit everyone including you, the tank. Resulting into unnecessary Overheal.
And Lakshmi/Susano cast a lot of mechanics and plenty of raid aoe. Also watch out for other relevant downtime.
