Give more arsha servers, make it where feeding to mobs isnt a thing, so no exp loss no crystal loss.
Have 5 Arsha servers like this and keep the one arsha server as it is now with the new 5 have no change in buff (compared to normal servers)or if there is make half the normal arsha server. Giving griefers more tools to work with to make everyones life hell isnt a smart idea but if your are thinking this is the best route then the above is the only way your going to stop a huge % of the player base leaving.
We cope with the karma system an got around it for griefers by declaring war , they started going guildless that means they didnt get guild buffs which was ook with us kind of but this also meant we couldnt dec them. Guilds that arent ready for war are level 9 there is no reason for this change.There is already protections in place why change it after 5 years +
Give more arsha servers
the issue here is, with the "crowded" status there is a direct indicator for which type of channels need more.
unfortunately, since the release of arsha server, that never happened even once, so there's undeniable evidence that there is no demand for more.
which means, people actually only want the arsha mechanic but fighting weak players, otherwise they'd use the existing already, but they don't because they are getting clapped there :-)
