@OP Patch 1.18 for many will be the "last straw". This to me means they will focus their attention that would have went to FF14 (if it were fun) onto something else. In they future they may give FF14 another look, but won't stress it.

Patch 1.18 for me isn't the last straw. It's another milestone (of many) that will continue to set everything in place to bring FF14 to proper fruition.

Somewhere along the line FF14 has already convinced me that a miracle isn't going to just happen. At some point you come to the realization that there's nothing you can do but wait, obviously. However, at another point in time you will get to the point where you just won't play the game unless you are having fun (but still read updates).
I've not been playing FF14 on a constant basis since January 21st. Having been playing the game since day 1 of Alpha, through to CE release & to now, it starts to take it's toll.

[tl;dr]
We'll just have to wait & see, but in the meantime I'm not going to worry about it since i don't play FF14 that much as is. At least not until they add fun.
