My guildmembers are not wasting valueable resources on stupid guildquests like the ones asking 30 wheels or 20 carriages. Also it took us some time to get organized as our beloved guildleader managed to do an disappearing act, making sure we couldn't cancel the quests we weren't able to complete.
I already complained to BB about the incredible stupidity (sorry can't be more polite) to make an guild utterly dependent on a single player, making upgrades worthless at the moment the guildleader disappears.
