It would be nice if there was at least one open only mission type in powerplay. It could be something like:
Faction A hires traders to run commodity M into station Z. The traders get paid for every ton of caego they bring in. Traders are given the mission commodity, they don't have to purchase it. It would disappear if the player switches away from open, or cancels the mission.
Faction B hires pirates or even random mercs to stop the traders from getting to the station. The pirates get paid for each kill and/or a small bonus for every ton of mission cargo removed from the trader.
Faction A also pays mercs for every kill of anyone in faction B. That way it's not just a trader slaughter. There will be protectors too.
These ideas are optional but I think could add to the mission.
1. Players taking part in the mission for both sides could have part or all of their insurance paid for.
2. There could be a corresponding solo/group only mission of running the commodity to the station where the open traders receive it. Kind of like a relay race.
3. There could be multiple commodities, some worth more than the others, but they all pay the trader the same. The idea is that it won't all be massive profits for the pirates. Sometimes they might catch a palladium ship, sometimes a copper ship.
Why do you need the traders?
Why not just a mission to go to a CZ and kill X number of players from the other faction?
Why does PvP always need a trader to be shot at?
