So high pop servers have stronger invasions due to having 50 in a fight and happen more often.
Low pop servers should have weaker mobs and the invasions should happen less. On my server most invasions are lucky to get more than 15 people to sign up and its literally GG. theres no way to keep towns upkept let alone be able to upgrade anything. Things are just slowly starting to bleed and downgrade and theres nothing that can be done about it.
