>.>; While this is my first time posting on here due to the sell-out, I'd like to make it as informative as possible. There are so far three tiers to Assaults for each area, Second Class Private, First Class, and Superior Private are the ranks. If you complete all 5 Assaults and talk to Naja, she asks for an Imp Wing, and gives you a promotion upon completion, if you beat all 2nd tier Assaults, she asks for you to investigate the "Dark Rider" and find evidence that he's plaguing Aht Urgan. I'm stuck so far on this, I assume it means the 'Odin' like figure that we saw at the very end of one of the clips for TAU, just my personal speculation, but from my knowledge nobody has gotten past this, it may be just being kept secret right now, or this may be the end of TAU missions. If I recall when COP first came out, it had less content than TAU excluding new jobs and the like, doing 15 assaults is like 15 mini-missions, which is a lot more than COP gave us off the bat.
Anyways that's just my 2-gil on the subject, if I ever find out more I'll be sure to post, but I probably won't be the first one

. By the way, the Assault battle music is a refreshing change to having same fight music in all new areas, seems TAU made a lot of people happy, guess SE did something right with this expansion, TAU music is my favorite ^^v.
