I decided to opt out on 5.83 since I like 5.82 better. The resources don't give you as much and armor doesn't work the same. I liked how armor gave a little defense against energy and missiles. That made more sense to me than just protecting against guns. Armor plating would have some resistance to energy beams and missile impacts where as shields or point defense systems really wouldn't protect against projectiles. I hope they change their mind on that one and leave it like it is in 5.82.
It also seemed to introduce some bugs with resources losing their colors in the map when zoomed out and the world list on the right losing it's planet icons.
I also didn't like the changes in AI behavior for the other races. I played as the Alterians with the Thalans as the closest empire next to mine. The Thalans ignored their own sectors for the most part and started moving into and over my territory. I ended up in race for worlds and resources with them. They were pretty far from their homeworld with many colinizable worlds that were much closer being ignored in favor of taking worlds that should have been mine. I've never had anything like that happen until I opted into this latest beta and I didn't like it at all so I opted out.
