I have seen a lot of posts about lack of content and that this game needs more PvP content and although more casual PvP content is needed, I feel this game needs PvE content more as a filler between PvP conflict.
The reason is that I believe PvP, in MMOs, should be a long drawn out affair with a lot at stake but because of that you cant really engage into those PvP campaigns casually so what you need then is some PvE content to fill the gaps.
Jumpgate building of different tiers. Each tier will create a stable, bidirectional wormhole to a PvE zone. It will create an endpoint either randomly, to prevent camping the exit, and later by controlling certain points, such as for example starbases (more on that below).
The PvE zone will contain various PvE content such as mineable asteroids, which will respawn once depleted, but more importantly, PvE mobs which have different levels depending on how deep you go into the zone and what tier your jumpgate is and they will give loot in the form of credits and resources. Later this could be improved if unique resources/loot is introduced.
The zone will also contain capturable, but not destroyable, starbases. These starbases will act as refueling/repairing stations but will also create a stable endpoint for your jumpgates and that of your alliances. You can also dump resources here for everyone in your alliance to use but beware, if a rival alliance capture the starbase they will then they will also get the loot.
This way you can at short notice just use the jumpgate to get into these PvE zones for some quick PvE action but also PvP as other alliances will also be there and fight for the control of starbases and PvE spawns. Effectively creating a PvPvE area.
