Ok, RP of some kind is a good idea. Most importantly background RP. Why would your Outcast shoot a GRN base in Il-de-France? They wouldn't really, it's not really a system they would fret over for something like that. Why would your Outcast shoot a GRN base in Tau-23? Simple, because Outcasts are not buddies with GRN and at all, and therefore does not want a base of that magnitude to be there.
Yet, for some reason with the way things are now, people are required to send full blown Comms to their mortal enemies regarding their bases.
If you were going to assassinate the leader of your country, would you write a letter to your government beforehand? No, you wouldn't, not really.
Therefore, I don't see why you need all these, specifically, forum RPs before you blow up a base.
More problems that come with having to forum RP are:
-Base owners can just complete ignore the post, leading to QQ, rage and hate which can then lead to unhappy players leaving
-Base owners can stall for time, base owners can get a base to Core 1 - 3 within a day...
-...Meaning the base could've been dealt with more effectively earlier, but instead 999999 battleships need to be used to take down the illegal/hostile base.
I only see that the base rules we have in place were only put in as a hasty measure to deal with the BH. Since they've been blasted out of the game themselves, the current rule only stalls and irritates the normal, fair players.
