I know theres a ton of guilds out there with different styles, Social Guilds, Hardcore/Midcore/Casual Guides, RPGuilds, Progression Guides
Im personally in a Economical type Guild, We have all the tools we need to reach whatever goals our members are looking for, and we use the marketboard as a last resort really only to sell to make profit.
A example would be - If a member needed some Darksteel Ore (which is a node that spawns 1AM at CCH) Members would gladly come over and help gather it if only 4 members did this we would produce over a stack of 99.
Its the same with Crafting, the Crafters help the Raiders with Gear, Potions, Foods, Etc. Where if a certain Crafter or Gatherer couldnt get through content Raiders would certainally help (Ie. Carrying)
And from there it goes full circle.
Believe it or not but it works perfectly at the end of the day everyone wins, and is only possitive.
So what type of Guild are you in or run? i'd im eager or know.
