Sorry @admin, but it is you who doesn't understand.
You have built an MMOG. The core defining characteristic of such a game is mulitple players, and tons of them. In order to attract and retain such requires in-game social tools (chat, dm, and most importantly, clans). If you want large, active, healthy clans to fulfill the core characteristic of the genre, they must have access to in-game tools to manage the clan. Warehouse and member activity logs, quick-look and single screen financial tools, and a functional two-way all-clan communication system.
Instead you continue to trivialise clan tools and actually go so far as to remove social mechanics in a social game! People may come for the combat, but it is the community that keeps them logging in. Time to fix it.
