We could have had some fun, relatively balanced wars going in EC. Sirion and Nivemus fighting Perdan. Caligus and Eponllyn fighting Shadowdale (after the Titans tell Perleone to withdraw). But then Perdan just
had to declare war on Eponllyn. Now Eponllyn is forced to cooperate with Nivemus just to defend its lands, even though Eponllyn's leadership's every intention was to respect the alliance system restrictions and not interfere in the Perdan-Nivemus war.
If Perdan didn't want to attack Nivemus through the choke-point, then Perdan should have declared war on Eponllyn first. Declare Troyes and Poitiers as your war goal. Heck, declare the entire Westmoor duchy as your war goal. Then it would have been Perdan fighting Eponllyn and Caligus, still a relatively balanced war. Perdan would have more nobles. Eponllyn and Caligus can attack from two fronts but also have more regions to defend. If any other realm tried to interfere, players from one side or the other would be asking the Titans to stop the interference.
But you can't dog pile unless there is a really good justification like the realm getting dog piled provoking every realm that is attacking them.
Every realm attacking Thalmarkin had perfectly valid IC reasons to do so. The Admins put a stop to it anyway.
If realm A + B are fight realm C + D, instead of jumping in to attack either AB or CD, you should go for realm E or F or others.
And Perdan is in the wrong for interfering in the Shadowdale-Caligus war. Had Perdan declared war on Eponllyn first, it would have been Shadowdale that was in the wrong, but that's not what happened.
