Broken down to specific elements you can see similarities anywhere but doesnt make it same or "barrowing concepts". Just my own 2 cents for what its worth. Personally from my toons perspective i would sort of hate to see a war between any combo of gardinia, uldah, limsa, or ishgard with all she "did" to bring together all the kingdoms but depending on how they do the story could be interesting. But again depending on the story dont make it BFA.
