So...Yugiri

[Tiggy]

Why in gods name do people continue to suggest Banga? Her posture makes that impossible. The shortness of her face makes that impossible. She is NOT a Banga. Seriously tails and ears are NOT enough information. Please try looking at more clues than that because by that definition Miqo'te would be Banga. Ridiculous.

If the new race were reptilian in nature, they would have a hard time explaining why you weren't being attacked any time you set foot in Ul'dah, or anywhere in Coerthas for that matter. Both Ul'dah and Ishgard are violently anti-lizard/dragon so making a reptilian playable race would be a hell of a stretch that would either require a whole lot of retconning or just completely ignoring/breaking the game lore.

No they would not. They have issues with DRAGONS not lizards. Even if it was a dragonish like race their war is with a specific set of dragons that live in the same region that they live in. Not with other intelligent creatures just because they happen to be lizard-like. You're taking the Ishgardian situation far beyond the data Square has given us to make some pretty broad assumptions.
