Lyth you made a very interesting post but, it's too bad that a construtive player like you fail to see that postional are in the way of FFXIV evolution.

Most of people wanting positional fail to see that's the SE lazy way of a making a job a little bit busy (not hard, positional aren't hard) and to not brainstorm and search for way more interisting and fun gamepay mechanics.

The game, job and encounter design, are tied down by the positional.

Getting rid or completly reworking the positional will open a lot of possibilities.... People wanting more positional are just holding back FFXIV gameplay evolution.
You need to let go of them for good... They outlived their stay and just are an archaic bad system holding back the game. (and the lazy way out for SE not thinking : "the job is not busy enough what can we do?".... "Well like alwats. Copy-Paste positional code and they will shut up")
