We All Won – The OGL Three Years Later

[Corinnguard]

I could easily see people playing D&D5e and borrowing parts of A5E...

I think that is the intent. Let the players get interested enough to borrow elements from A5e for their 5e games. While some players will stick with 5e, others will Level Up.

I also don't know if in later books A5E moved away from the OGL, looking at Morrus's comments, I seriously doubt it.
