WAR's 2.1 changes.

but PLD's damage output was not that low compared to WAR.

PLD is still the worst DPS tank ever since 2.0, no matter how pretty people want to word it. I can guarantee you when SE releases a hard DPS check like Gordias, people will complain again. PLD is by far the most played but all of tanks the worse DPS dealer. Midas has been great for PLD/MNK (added safety) setup so far since DPS checks aren't tough at all, let's see how it holds to the next raid patch.

See logs if you aren't convinced at all. It's 100% truth that PLD sucks at DPS-ing.
