Is it really as simple as spamming savage>riot while keeping roh buff debuff up if needed?

Also. I assume appropriate times to be in sword oath are when I know I'm going to be dpsing for awhile and don't need to pick anything up/when I know I can take the adds while in sword oath?

Kind of trying to get down all the info I can as I'm not an extremely experience PLD (or tank in general) but for the sake of forming my own static, I will be tanking for it. (Starting on bcob)
So I want to be prepared as I can be.

Any help and tips would be much appreciated, thanks.
