I would request clarification about the "characters" vs "player" change.
Situation:
Quote: Player X attacked ship A in T23 and got killed.
Ship A leaves T23 (e.g. because it runs a convoy / a fight shifts to the next system).
Player X is still angry...
Old rules: Player X could not touch any ship that were participating in his death on all his ships.
=> If he did, he was open to sanction.
New rules: Player X can log onto his next ship and attack again. And again in the next system on a new ship. And again in the next one on yet another ship.
=> Even though you know it is the same player, you could not sanction him according to the above mentioned rules.
Remember the wild indie Hogosha Kusari days? 10 Gbs, spread everywhere. Every one could now engage again, even if you know that the same players are behind it.
Imagine the trolling potential when you just have to bring a different ship and pew the same ship again.
