Alright Guild challenges 

Daily weekly and monthly.

there can be all types combat life and misc. Everyone in guild can work together to beat common goals for rewards. One of the basic rewards would be Guild funds but also silver and some loot boxes or random items depending what you beat. There could be tiers of these also for daily weekly monthly. Gives everyone common goals in the guild and rewards everyone for the effort by all. 

challanges could be kill x enemy gather x timber enchant x there's so many things to do this would also help guilds that are smaller build there bank up more to have payouts be half decent down the road. I would love this honestly rewards for effort man no brainer.

Yeah I agree there should be more group content for those that love to play together.

I want...

Guild fishing quests...

MEANINGFUL ones. Not- "Go catch 50 grunts in bal sea"...

More like, "Go harpoon 10 ghost whales in 5 hours" get 180billion silver as guild reward. 

"Go fish 200 relic fragments in 5 hours" get special ancient relic guild summon x 10.

"Go fish 100 broken sail pieces in 5 hours" get 20k crow coins.
