I go through X-ethers like candy on all my mage jobs, and also on my bard. Just wish the cooldown was shorter.

I also use Buttons in a Blanket as my universal food on all my jobs - got something that benefits everyone, and I can make them cheaply myself.

The rest of the thread has already given a pretty solid point by point takedown of everything in the OP, but I did want to add in that I'm on a very active social LS on my server but my FC only has around 15 active players, so having the social LS fills in the gap when no one else is on. Makes the game less lonely.
