Rogue/Ninja Starting Class?

[Erudain]

Even if they add another teacher for you to become a NIN at lv30, it still wound't solve the plot hole with Thancred/Yugiri fight scene....everyone and their mother were surprised to see Yugiri fight style, so one can logically assume it's the first time they are watching it.

This wouldn't make sense if you were using that fight style since lv30...Y'shtola would had seen it in the Titan arc, Cid & Alphinaud would had seen it in the memory loss/Coerthas arc, and finally every Scion would have seen you when you saved them from Mor Dhona castrum...
