Is this considered an exploit or not? (Re: ephemeral node respawning)

[Valkrinos]

I know that the trigger is opening it, not actually gathering. I'm trying to find out if that is absolutely intentional. It seems like you'd be intended to actually mine out at least two of those nodes, though that isn't the way they programmed it.

As an example: http://forum.square-enix.com/ffxiv/t...-node-behavior I'm not the only one who thinks this seems suspiciously easy to do.

If this is absolutely intentional (how simple it is to respawn) and not an exploit at all, that's completely fine, and welcome. Just was hoping to get some sort of official confirmation.
