There is no profit to get paid through gold by the owner of prisoner, it would be much more better to provide an option to select the form(gold,guild coins, gems,resources) of ransom.... Please provide this one
Gems would render the gift button useless. People could just create f2p alts and send themselves gems. Gold is pretty good to me, you can always try and sell it or give it the guild bank if you don’t need it.
