Looking at BLM's Merits. It seems that its mostly based on personal preference on what elements you like. Then possible which ever two elements you choose for Group 1, you'd might do on Group 2.
But which are recommended?
Just thought I'd ask.
I might handle blm slowly now since I'm trying to get Water,Aero,Blizzard, and Fire IV but they're 200k+ on my server and the drop rate for em are......well.... you guys know....
And I don't want to go in a party without those spells.
