There should be a point system for clan that killed many bosses and ranking on server.  These points can be turn in to learn clan skills which can benefit all clan members 

This will give clan members more incentive to kill boss daily 

Also the clan boss key should be increased to 8 per day with limit of 8/8 for example not 2/2

Please have to work in real life so for them to accumulate keys then kill all the bosses when they have the time that day

Also clan that rank top 10 should have special clan reward skills for all clan members 

Clan can work to improve the level of clan skills 

Please improve this
