I can imagine Archicad having trouble on El Capitan due to the nature of the app itself. Not everyone can upgrade to El Capitan right away. But my guess is that SquareEnix and Transgaming are betting on the Metal API to get a better client for OSX.
Fun Fact: Transgaming removed the article about releaseing FF14 for Mac from their website.
We'll have to wait for SE to announce something. I just wish we had at least some vague info on the future of the OSX Client.
