My build is very different, but yeah, I also really think Wind is the strongest element. It's by far the most versatile. Maybe that's not true anymore past Ch 2, I dunno... not a Patron.
That said, there's... actually nothing preventing you from changing your skillset before every fight, so it's entirely possible it's best to have multiple sets that are really powerful at specific things rather than one hyper-versatile set. But I'm pretty sure most people don't swap their skills before every fight.
