The main purpose of this server is Roleplay. Everything else is secondary (combat, trading, etc...) If you want to PvP non-stop, take it to Connecticut (which is what it was created for) or take it to a different server.
Your point about things being repaired at the push of a button... inconceivable. Does not make any sense that commodities would need to be traded if you could just create it with a push of a button. (if you can make ship parts at the push of a button, why not food, water, metals, etc...) ALSO, even IF you could repair a ship at the touch of a pretty little button, how about the pilot? There will never be any instantaneous cure for any aliment or damage to a person. It is physically impossible, and would not be beneficial to anyone. Human beings need TIME to heal, no matter what type of injury one may have inflicted upon them.
As for reducing the time limit for re-engagement, that has been done (for a short period, it was 2hrs not 4hrs) however that was reversed quickly because it was abused. Players would be engaged multiple times by the same player in a single session, over and over again. Thus, not being able to create any sort of inventive RP (and was rather annoying). conversations ended up sounding like "Back again for more?" "Yeah, enging pewpewlolz."
