On top of it all, PLD does have a much higher learning curve. The use of Cover, Holy Succor, and Divine Veil are really nice mechanics, but they seem perhaps... too intense for the current environment. Cover is counter-intuitive when you're supposed to generate so much enmity. Holy Succor is an amazing Cure spell but again, are others taking enough damage that you'll heal them for 900+ to make it worthwhile to cast when you're holding hate well? Divine Veil is kinda overshadowed by Prism+Regen and allowing them to stack works against your Holy Succor idea.

You can understand all of these things and play PLD like a badass and still be left wondering what it was all for. I think most would rather just DPS while tanking and let the healers heal. Sad but not far from the truth.
