Dynamic A.I. in Future Destiny Games

There have been tons of debate about what we all want to see from the next Destiny game. I'm not going to go into all my crazy theories but one of the things I personally would love to see is dynamic encounters. Every story mission and strike, even the raids, all the enemie's behavior is scripted. Meaning, you always know what's coming next. In story missions I understand, but Bungie talked about how strikes would be different everytime because of the fact enemies would spawn in different places. Nope, same spot everytime. What I would want to see is different enemy spawns and in different locations. I don't expect to see the Hive on Mars (although I would like to see that kind of variety), but since this game is based on replayability, that'd be a great addition and would make the grind far less repetitive. Thoughts?..
