Why is there all the Delirium Blade is useless garbage? Dragon Kick was amazing in T13, and now if you don't have a MNK you can bring a DRK instead. Or for Savage A1 you can bring both and put the MNK on Oppressor and have the DRK on Oppressor 0.5 and you have INT down on both mobs for their HUGE magical tank buster.

TP on DRK sucks, but that's not new, PLD/WAR (outside defiance) had the same issues pre 3.0 and PLD still has those issues. I do think it's a little ridiculous that WAR has unlimited TP now, except in AoE situations where a DRK that is tanking can just Blood Price and spam for those 15s, basically free.

WAR is still a lock for a group, Storm's Path is irreplaceable, and then it's really up to the group whether they want more defensive utility or offensive utility, as far as bringing PLD or DRK. With the current savage DPS requirements bringing a DRK seems like the better choice. That doesn't mean it can't be done with PLD, obviously it already has. With the plethora of magic mechanics in savage though DRK shines pretty bright.
