Issues with my almost satisfying experience.

Currently i am playing as Terran on insane map size. And i found these issues.

1. I have noticed that my Knight M1 cost durantium. It is a generated ship. Since it cost strategic resource i expected to have a name that starts with Prototype like other ships

2. Specilizations in tech trading. The issue is that specilization specilization is locked on 1 choice. If you specilize in 1 direction you can still trade other Specilization. You can exploit it by going into a trade screen and research one that isn't avaible. To this issue there are a few possible options. a) On a start game screen Have an options not to be limited to 1 Specilization. b ) A trade screen doesn't show Specilizations in a group that you already have reseached. c) No Specilizations trading, only non-Specilizations tech. The player needs to Specilize themself

3. It is very hard to know when i can trade with an AI. Sometomes i go to their comm screen and only to see that trade is grayed out. And tooltip say "You must wait longer to trade". I would like to know how many turns more until it is possible. I would like to see icon in a power tab to see which one is tradeable.

4. Early game I am having pirate problem. My scouts sometimes find Pirates shipyard. Since i am uneqiped to handle i ignore it. But when i can handle i can no longer find that shipyard on my map. I learned this by hard way. So i use rallypoint to mark a point of interest.

5. Insane Map: Clustered type feels so empty. There are a few stars close, then betwen them it's wast of nothing. Even with very slow research, it feels it's fast

Overall I enjoy overall experience. Issues #2 begs me to exploit. Even if i try not to do, i can easly click and get it.
