Looking around the forums it looks like as there are nearly 1000 kingdoms, and say 500 towns from each kingdom goes to Jontrnheim then thats half a million jarls all hitting the invaders ans ghosts at once.
I think that's why it's very hard to see one let alone get close to it and score points.I have ready conflicting theories about the trolls. One theory says there is only one troll at a time in Jot' which is why they are hard to find, another says there are a lot but the lag is so much when you see a troll it has already been killed.
Like to say there is no reason at all why Jot' can not have as many trolls etc as a home kingdom. They would skill need a lot of energy points for a small reduction in their health.
I find it hard to believe that Plarium would be against having more than a few Jarls get the loot drop from the attacks but that is what is seams like.
