I went with the Twin Adder GC in 2.0 after spending a long time as the Malestrom GC in 1.0. I had half thought that if I joined the Twin Adder that my rank and gear would carry over or be usable. Now i'm sitting in the Twin Adder GC at the lowest rank and all my Malestrom gear is unusable - which I had counted on for my level 50 characters. It would have been nice to have a warning before doing so. Or at least make it easier to walk into a GC and change companies. I didn't know I had to reach max rank to do so, so I guess I'm stuck in the Twin Adders for a while. My GC chocobo hasn't switched colors when joining the new company, so that's another thing to wonder about.
