Basically - Fuse the Invasion with Sector Conquest and PvE.
First thing that comes to mind - Dreadnoughts.
Your corp “Invades” Sector X (First come, first serve).
Then another corp challenges your dominance and attacks your Dreadnought with theirs.
In the end one Dreadnought is destroyed and One of the 2 corporations reaps the benefits from the sector. (Like 10GS/h ) as long as their Dreadnought is not destroyed.
Every player who is not from either of the corporations is instantly red to both of corporations’ members during the war.
You want to go through a war zone ? On your own risk!
You want to help one of the sides ? Like mercenary? You have to sign a contract with one of the officers of either of the 2 corporations. (like invite, but with clock on it)
They will pay you with 20% of what members benefit per hour if they win. If they lose - you lose your time (and life) too.
But that instantly pops a warning - I have no idea how to manage time zones.
ex. WPK getting a sector, then while they are sleeping NASA gets it, retaliation and vicious circle of destroyed Dreadnoughts and loss of resources.
You can dock and launch from your Dreadnought.
What happens with the resources you farmed while docked on Dreadnought that was destroyed ? You keep them. They magically transfer to the station of the conflict’s side you are on(The corporation), as well as you.
When we switch stations now all our resources travel with us. Magic.
Only one per corporation, so you have to chose your sector. May be for sector benefits (10GS/h for the highest one) or simply to help your corporation mates farm resources/synergy/blueprints easier.
Remove PvE as a mode and reinforce people farm bots in Invasion instead. (add some synergy gain in invasion too)
That way we have : Invasion, where people hang out, farm, kill each other, corp war over a sector.
and Arena mode - like the good old PvP.
Only 2 modes. One PvP arena and one universal for everything else.
After all - “End game Content” ?
