Don't try out WAR/PLD LFP, because nobody will take you. (Maybe before Yhoator). PLD/WAR is the one you want.
Unless NIN and /NIN still holds sway in the tank department? Or did everyone get over that yet?
They are still not over it.
For merits it's better for sure.
Most of the time I prefer a PLD tank while progressing through levels though.
And NIN or /NIN before 37 right out sucks anyway.
