Still really hard to make freinds in diplomacy...
I had a way easier time making freinds in vanilla sins. Diplomacy is making things much less diplomatic. One of the main problems Ive observed is that good things you can do to make positive points give very small bonuses and fade really quickly. I did a mission for an AI and by the time they got around to giving me another ALL the good points I had gained from the first mission were already gone. In contrast things you do that piss them off, Which includes defending your own planet when they attack it give a lot of negitive points and never fade away. Plus if they are a different race you start with a huge dificit anyway. Plus they tell me that I have 3 negitive points for "Military strenth" and I have a much smaller fleet than either of them. The special abilities are great but dont seem to have much effect (lost many envoys trying to get some positive score). Plus despite shooting at each other for the first part of the game, they suddenly were able to forge a ceasfire and attack me. So here is my sugestion. Reduce the amount of negitive points given for most grivences and have "military action" negitive points fade quickly (obviosly it should stay a bit longer if you actualy conquered one of thier planets) if you go a while without shooting them. Also eliminate or revamp the "Military strenth" so its not trigered just by you having 2 cap ship and 5 attack frigs (they both had 3 caps and large diverse support fleets) and severaly reduce the "race relations" point modifier (cause some of us dont like playing with 3 TEC's). And Finaly make the diplomatic powers of the envoy count for A LOT more, that way if a player sacrifices military labs for civil ones cause they want to play the diplomacy rout they can be effective that way. On that note bring back passive imunity for envoys. There was really no reason to take it away, and currently they get blown away before they can have any effect.
