100% PDT for PET is plain BS.

[Cyranda]

Having a pet hit 80% PDT (which is quite easy to attain), is still an incredibly good tank, better than most player characters could be. Even if a perfectly geared and fully def-buffed PLD were to eat a 1k base damage hit to the face, it would be hit for maybe 400 damage. A pet would take 200 (twice as good), with a PDT set that isn't any challenge to attain. Some may argue even that is broken, but I wouldn't mind it. All I'm saying is 100% PDT makes no sense whatsoever.

I certainly think there are more elegant solutions to giving some jobs advantages where they currently lack, though I think it would make less sense if it also didn't essentially make the BST hit like a cotton ball. Getting 100% damage reduction isn't too badly balanced given the work one has to put into getting it, the return on the investment (low) and the gigantic waste of time it is to solo something using it, especially considering how jobs that DON'T have it, with some exceptions (I'm looking at you, RNG and PLD), can get gear faster and wouldn't actually trade their proccing, stuff-getting status to get 100% PDT, slug-speed killing and poor returns anyway.
