Thing to note about decisive strike that tends to be overlook... it's a full round action, not a full-attack. And as such is eligible for dividing the action in two standard actions over two turns. What is interesting about this? This actually allows you to move and attack, using your monk speed and decisive strike together... something that our poor little brother flurry of attacks cannot really do by itself. That alone makes it so much better class design than the base... truth is, the monk really suffers from their kit pulling them in very different directions, it's nice they have something like this to unify their playstyle.
