I highly doubt that can be done server side.

make the hack points raider objectives. You can control the objectives to gain salvage (Preferably salvage you can use) and ISk rewards. Make them hackable once every what, two, three minutes?

This totally wouldn't cause performance issues.

No but you are proposing removing the vehicle limit. There is a vehicle limit in skirmish for a reason, and it's server performance, hell the game has a hard enough time running the science research center, I'm not saying a new mode is impossible, but increasing the map to over 1km would require Ccp to rework how the ps3 loads everything, unless you think both the server and the client can handle preloading that much space with loading that many vehicles. Plus it only partially renders it in the distance, not fully.

Ok i like it but, salvage... i cant sell it. If im spending isk in a match like that what is the isk payout? Is it 50% of what i spent/or killed. Or is it paid back in-full of what i lost?

Unfortunately, devs avoid these convos, not necessarily intentional, more due to the large topic spam here on the forums.

hmm so a persistant battle.. what about sp/isk earned? paid upon leaving the fight?
