Hello BST .
This is Katra of Leviathan.
A quick summary: I started playing XI at the PS2 release, but I didn't play BST seriously until a few years ago, which was a few months prior to the patch that removed the exp penalty from keeping charmed pets at the end of fights. BST was actually my first job to 75, although RDM was my first job to break 70. Although I broke 70 with RDM, I had so much fun leveling BST, at that time it was around level 13, I took it straight to 75.
BST had also made me a fan of pet jobs in general. When I started, I preferred playing as mage types, and since RDM gave me a bit of everything, that was my first main. But BST gave me a sense of freedom and satisfaction not experienced with the other jobs, and as such, it became my main, and has remained such ever since.
Go BST.
