I'm also pretty sure SE will never add so much SMN skill gear that we will actually be able to get to the full 60 seconds of Perfect defense (as if it was that gamebreaking to give us those 6-7 seconds more duration). I was pretty unhappy with that notion back when it was changed (not that it was changed. 90 seconds was pretty broken imo).

SE always holds a carrot on a stick right in front of us, but we'll never be able to catch it.

They just don't seem to understand how far behind we SMNs are compared to most other jobs which doesn't have to be the case if they would listen to us who actually play the job.
