A day or so ago I was describing my beginner atttempts at tanking and I'm happy to report that my first full attempt at a dungeon resulted in a nice, smooth, easy win. I struggled more to understand the French spoken by my teammates (and even answer at times in my terrible never-actually-studied-the-language pidgin) than anything abttle-related, and can also report that Shield Lob was completely unnecessary, so the goofs I got stuck when I joined at the final boss of my first dungeon were probably just incompetent (and, rather than having been ditched by a bad tank, were probably given up on by a normal tank).
Loving this tanking so far even if I know it will soon get harder.
Regarding rare market goods: My retainers brought back a Goldenfin (green-icon fish) and I looked it up on the market board only to find that none had ever been bought or sold. Listed it for 60,000 gil and after sitting out there for a long time, it sold. I still don't know what it does. Maybe I should have asked for more.
Regarding PVP: Is there a way to set up pre-formed teams in Frontlines? If so, any Immortal Flame GAFfers interested in forming one? I find myself enjoying Frontlines but am still very much a beginner -- I still have no idea what's going on with the "drones". This could a tremendous amount of fun if we were well-coordinated and could learn together.
