I wouldn't mind having some server setting options regarding the wards. Options like how much they can reduce damage to structures in range (100% would mean indestructible) or at least different settings for PvP vs PvE selections. That way if you want to play PvP it can function how it currently does so it's possible to destroy the ward and raid, but if you want to do PVE, it can nullify player damage at least. Although PvE would also imply that mobs and raids could still cause damage, which the griefers among us would almost certainly take advantage of, especially since troll mining/logging is already semi-meta.
