I feel like the part that makes me go "hmm" is the part where people want to invite the pld FIRST. The game is too easy to worry about how efficient each member slot is? The tank who increases the party's kill speed does not outrank the tank who... tanks? I am not too worried, as every duty finder I've entered to this point has been literally instant. Coming from old ffxi, where a ninja dealing damage like a true DD is a party champion, and the pld can level another job if he wants merit points, this sort of logic really confuses me.
I guess it makes sense if dropped to half health, then the healer needs to move before he can finish casting, then my health gets dropped again and death follows. Perhaps I should just embrace it, level pld as well and be damn thankful that the jobs share 90% of the same gear. Or maybe I shouldn't be worried about any of this if everything difficult is based on rather or not people can avoid flashing red icons on the ground, I really don't know at this point.
