Paladin Shield/Sword Oath Usage
I'm new to tanking in FF. Without a doubt, it's different than what it is in WoW, which is what I'm used to. It took me awhile to adjust from WoW's "tanks are complete defense" mindset, to changing to FF's "tanks are enmity-holding dps" mindset. Unless I've completely misunderstood what I've been researching with this.
Regardless, I've found myself enjoying paladin over warrior and drk. I've done my research on combos, rotations, how mt/ot works, and so on... But there's one thing I keep getting mixed answers on, that's causing me the most confusion.
My question is when to use shield oath, and when to use sword oath. If I'm tanking a dungeon, do I just permanently keep shield oath up for enmity, or do I use sword oath to get my gauge built up faster? If I'm main tanking a boss, do I always use shield oath... Or do I only use shield oath in times of high damage, sword oath during the rest?
I've been getting mixed answers in my research, and was hoping to finally get an answer.
