EVE doesn't have gamemodes, so what?

does eve have instances like in most other mmo's

No, it's all one big instance, that's one of its selling points.

Also, there's EVE Valkyrie already

This is a game mode that both Eve(game) and Dust 514 will have added to each other and play directly with and against each other. Players battle in the Thermosphere and try to destroy or capture defending teams space station base while the other team try to destroy the attacking teams warbarge. Many Different mini space ships to choose from with different roles to play each from transport to attack. Battle last until the defenders main space station is destroyed or captured, or until the attackers warbarge is either destroyed or captured. this could be placed in FW and expanded into the first part OF a 3 or four prong PC attack because PC should function like rush in battlefield. so what does the community think any add ons would be appreciated.

I honestly cannot see EVE Pilots and Dust Mercs. coming into direct contact in any meaningful way.
Eve Pilots are in Space Dust Mercs are on the Ground.

Fighting over Space Stations or Player owned Structures (POS) is possible but these interactions would be initiated by actions in EVE, and they don't happen every day. There are long periods of inactivity where Sovereignty/Station change of ownership and POS bashing is concerned.

Any game mode involving fighting on Stations/in POS would have to be entirely artificial with no input from EVE side, otherwise Dust Mercs could go for months without ever having a battle available.

Nice idea all the same. I just don't see it happening.
