Somewhat OT, but related to the island AI, game AI in general and innovation.
Here is a session on an upcoming event (GDC) on how Valve are using deep learning to combat cheating in CS:GO:

This is an example of innovation I'd like to have in WoW. Not specifically fighting cheaters, but, say, making an actually smart set of mobs that would roam the continents, be interesting to fight and hard to defeat not because of their humongous stats, but because they simply are more coordinated and use what's available to them (buffs / debuffs / can add much more) better than players do. Imagine an old god faction rising up and pwning the Horde and the Alliance for real. Not by stats, but rather by making good decisions. And imagine that not being temporary - with each realm having to actually take cities or hubs from that AI army and having plenty of potential to lose what has been gained.
That's how big things look like, not this bleak "okay, we are going to move talents from one-item artifact to a three-item artifact".
