100% damage reduction makes absolutely no sense. That's a PLD's 2hr, which (duh) you can only use every two hours. For a 30 second duration. Having BST and PUP fulltime it is just silly. 80% I can understand, and in fact I believe that should be the cap (for players too). And yes, as was pointed out, Abyssea is a time-sensitive area, and even if it wasn't, watching a guy tickle a mob down for 90min and more when you wanted to do that is not just generally disappointing, but also against the spirit of Abyssea, which is to make content easily accessible to everyone. People complained about 3min respawn timer for ???s, but having to postpone a NM because someone is AFKing it to death for longer than you can even stay in the zone? It's like soloing Genbu in 5 hours. While it's possible, and kudos to you if you have that much patience, it obstructs content for everyone else. It's simply unfair.
