Alright, all fair enough.
And I do fully agree with being able to upgrade gear through crafting. I've seen it's use numerous times even just in the low levels of XIV, and hopefully that trend will continue

.
However, if you want the level of NM's found in XI, with spawn times and multi-hour fights...
For the love of gods,
instance them.
Fighting over spawn points is not competition, it's asinine, and a fool bit of game design. By all means, make people work to both get to the boss and manage to defeat them, but don't make them fight the very community for it, that's nearly as bad as PvP.
There are so many options, so many paths, by which to handle things like this, there's no reason to create tension amongst the players over it.
