I personally would love to see Overseer stats, progression and agents move with characters when you transfer. I have a few characters I have to leave on one server because I don't want to lose all the progress and agents I have and the money and time invested in them just to move them to another server. May be a limited amount of people that this is an issue for but with server transfers, TLPs running their course and people wanting a fresh start or to consolidate to one server this is an issue. I would pay a reasonable price on top of the server transfer token in order to avoid losing my agents, progress and stats.
this would also make sense , being if you order the package in Marketplace and get the Fippy Darkpaw Elite Agent its a one time thing for that account .. so if you transfer the toon you claim him on to another server you loose him .. which would sux ..
