Ok but put something together that makes sense for fixing it. Just raving about High sec PvP is getting nothing done. The OPs original post has nothing to do with actually fixing the war system, and most of his points are fundamentally wrong.
I would put to you that the structured setting of high sec is never going to be war friendly. Wars in high sec will be structure bashing.
The protection that high sec gives to aggressors is to large for any sort of genuine fighting to ever take place there. Large fleet on fleet combat will never be part of the high sec warfare game because it is in almost every case a larger/more competent organization taking on a smaller/less militant group.
Yah the War system is pretty borked. The idea that people can leave corp with an ongoing war, and be completely safe is silly.
The sort of warfare I believe @Pheonix_Jr and @Ralph_King-Griffin are advocating for has a place and it is not within the laws of high sec. You both seem like competent people so please understand nothing I have said above is meant in any sort of malice just pure frustration at the constant raving about high sec needing fixing because it does not suit a players choices when a place that does suit their choice already exists.
