Fine-Tuning PLD rotation - tips?

[Sarcatica]

I'm curious as to your thoughts on how ShO is a weaker IB o.o

If you are looking into the best scenario for tanks, ShO/Grit is a weaker IB indeed, you are losing damage potential from each gcd consumed when switching stance. In the highest lvl of play, WAR don't even use Defiance for too long when pulling, much less Unchained.

You are free to look at the top speedrun parses via FFlogs for convincing data.
