The Dantelion Plan

Ganking
Ganking of mining ships is fine, people have options and the ship that Alpha’s use is so cheap that it does not matter.
Ganking of freighters, JF’s, Bowheads and Orcas would be fine if bumping was capped in some way.
Ganking of DST haulers etc. seems fine.

Loot scooping via a DST is broken, needs fixing.
Balance change is remove docking rights in NPC stations if -10, this is to force the use of citadels for prolific gankers to create content and a point of vulnerability.

War decs
Mechanics are mainly fine, needing the following tweaks.

Enable defenders and their allies to be able to rep each other in a war dec without going suspect
A character leaving a corp that is war decked will bring the war dec with him to another player corp if he joined them in the week of the war dec, however the period of the war dec is to the end of the original war dec, so if he joins with one day left, his new corp only has one day of war dec. EDIT The attacker CEO has the right to accept or reject the extended war dec from this mechanic to prevent an obvious (I missed it) exploit by more devious war deckers.

The watch list was too powerful and it was correct to remove it, either give some online data with locator agents or do it in another way, but do not make it so easy and powerful as the watch list was, that was broken as hell.

The OP has suggested a war room, I have suggested a Concord agent in a citadel.

Game balance is the issue with hisec, blanket war decs are disliked intensely by many hisec players as it is deemed to be a waste of time in most cases. it is imperative that CCP look at ways to change this by adjusting mechanics and risk to change player behaviour. The OP suggested a war room and I suggested limiting war decs to 5 unless you have a CONCORD agent in a citadel who enables you to run more via him. The details of my suggestion are above in this thread, my objective is to create consequences for war deckers, and this is really needed, and enabling 5 war decs for smaller groups will prevent small entities from being blocked by bigger groups.

Social corps for new players should also be introduced.

Making hisec a no-PVP zone is not supported by me.
