A chance to really shake up and improve on the quests here, for example, remove the "pay weapons" from the GQs seeing as we no longer receive them from the loots.
Listen to feedback and consider before asking for expensive resources for a handful of guild coins... GQs should be about cooperation between members, so mutual buffing and yes, even adventure sharing would be more in order than payment of resources.
In fact, why not take this opportunity to actually ask your player base for some inventive ideas and then put the best of them to the vote for inclusion into the new quests?
