Contract System. All is fine. However, developers never introduced one very important feature that I suggested in the past.
Each individual contract should have the option or a tag, to describe where it can be completed - PvP only or PvE as well.
Example:
Destroy 30 interceptors.
PvP only tag
Reach 1500 effectiveness points.
PvP and PvE tag
Or just one additional sentence. Take your pick
This contract can be completed in PvP only or PvP and PvE.
Please, consider this. Many people do not know that you cannot complete certain contracts in PvE.
