I've had a solo FC for 5 years now and I've never built an Aetherial Wheel. Am I missing out? When I'm like leveling jobs or whatever, I just pop a Squadron Manual instead because I have hundreds of those for Exp or for MGP.

Is there any real reason for me to build an Aetherial Wheel at this point? I see there is some crafting buffs, but honestly I don't really craft. Are those buffs pretty impactful for crafters?
