Crafting and Mog Garden and Skill ups

I think there was some major oversight in something crucial to crafting... being able to use clusters in the mog gardens. I can craft for days in my mog garden as long as I use all the clusters I plan on using outside of the garden, but I think it would be more beneficial to actually be able to break them inside of the mog garden.

Another thing... couldn't it be possible for us to stand in our mog garden and say... cast enhancing magic and stuff on our selves to skill up? We have this whole private island to ourselves that could have much more potential. Mages could grab Ionis, head to their island and skill up their magic of choice (enhancing, healing, geomancy, handbell, instruments, blue magic) all without having to exit out into the wild to spam spells to skill up.

Being able to break clusters into crystals inside Mog House/Garden would be usefull. The other thing... not so much.
