I think about half of those changes were enough to 'fix' the job. The rest... are just stacked on top of them.
Honestly, tying the healing bonus to defiance instead of wrath, and adding -PDT to Storm's Path was probably all it needed. Then they just kept going. I was a little worried that they would just make WAR into PLD and give them the same flavor, but I'm pleasantly surprised with how they kept the theme of the job.
I expect PLD to get Cure II this update and maybe some numbers adjustments as well. Really, all the jobs will get some balance changes, this is just the only one that's being significantly reworked.
