I will think about it.
At the moment it is indeed part of the warp risk as an additional, comfortable and free way of traveling. Some risk has to be involved, especially thinking about movies or the Freelancer Game where you never know what is on the other side.
Make sure to warp the normal way, destroy these bases and then use the Supergates again.
Or new player can pay a “Security & Guard” fee to PvP factions to get rid of them. (similar to the stuck => ask Alliance for help mindset)
I would really like to see more “issues” are solved with roleplay rather than rules and rules and limits left and right.
