In these examples we have Feds vs Klinks and here's how it's happening:
1.) Ok I'm a Fed sitting on a Fed controlled Planet. A klink moves in and the mission choice the klink is given is always a patrol.
2.) There isnt a fed sitting on the Fed planet. The klink moves in and is only offered PA scripts.
3.) A klink is sitting on the Fed controlled planet and my Fed character move in and the mission choice I get is always a patrol.
4.) No one is on the fed controlled planet and my fed character moves in and is always offered a patrol.
Those are the only 4 things that are happening. So PA scripts are not offered despite being a PvP mission. I'd rather they not be PvP missions because drafting a live player while facing 3 Defsats and a Ph4 armed planet would take forever to complete. That's not a balance issue I want to contend with.
There is room for improvement. To answer your question in the above post, my sugestion would be to offer a script for friendly space planet hexes where you control a neutral base, Defsats or such along with up to 2 other UI Fleet Controlled AI ships, each AI spawned based off of whether or not you face more than one opponent. Course, this mission should be rife with AI ships on both sides. AI ships make things interesting. Anytime you add a base to a PvP script, that just does away with the non-AI pvp crowd. I prefer straight up AI stripping patrols when given the chance.
Another script that has been skipped in previous SG servers is the Shipyard Assault/Defense. Again, I like how the current setup works in which if there is a draftable opponent you are only offered a patrol. In the case of not having a draftable opponent, ShipYard Assault/Defense missions would add variety and fun. Basically, the PA and Shipyard assaults shouldnt be PvP missions. Currently, the PA script is just such, only an AI mission.
Another area of discussion on this is Chuut's comments on running 4 missions in the defense of one's planet in the time it takes the assaulter to do one. Perhaps Planetary Defense missions and Shipyard Defense missions should become standard fare for friendly space planet mission choices instead of patrols. That'd level the playing field making it just as hard to defend vs AI as it is to assault vs AI and leave the PvP to patrols only with AI stripping. I'd preder this setup as ideal.
