Also to note about Ascension crystals;
-You are only able to obtain points from 5 of them. Early in the beta there were more than 5 in the map, yet if you had 6 in your possession, you only got 5 points a week. I don't think I've seen more than 5 crystals on a map though since they first beta they implemented it, but that also may be because I mainly play on medium maps.
-I you have only 1 crystal in your possession, you'll get a - from all races in the game for attempting to ascend. If you have 2 or more, you'll get a -- from all races. The very moment you no longer fulfill those requirements for the - or -- I just mentioned, the negative relation goes away. That will allow you to get a temporary reprieve from everyone by destroying/selling those bases thus no longer attempting to ascend...even if you're only 10 points from winning lol.
Habitable Planets...are you on an immense map? I think the planetary count got either capped or somewhat scaled by map size and on immense there was a significant change in amount of planets vs size of map.
