So really, we're at the point where the leg between the Legacy and the not-Legacy player is becoming nonexistent.
I'm on Leviathan and I already have 7 masters, working on my last one, plus 2 master gatherers as well, (I really dont like fishing LOL). Plus the mb always has about 4 of each master craft up most of the time so I would say not many people have it yet but its getting there. Lots of gil and time invested in it for sure!
