Just a quick question did the PLD go in with Shield Oath on?

I ask because in lvl 50 content generally the PLD is the one who is main tank due to them only having aggro combo. War generally takes off Defiance and uses buff/dps combo. My only guess was they were fighting you for aggro in shield but because your il was much higher that they couldn't match it.

Either way based on what you did you sound totally fine. Tanking is a lot of fun, it's just at the LVL 50 and below mark the only tank that actually makes sense is DRK as it can either go into tank stance or dps stance while retaining it's toolkit at that level. PLD and WAR were made pre 51 with the ARR mindset so a job like WAR doesn't get a dps stance till 52 and PLD doesn't get a different melee combo until the Goring Blade at 54.
