Only being able to see the top 3 players in a clan progress really hinders a clans progression, Being able to see the full list of how much EXP everyone within the clan has received would greatly help clan leaders. THat way people that have quit/ are not active can be removed to continue grow your clan.

There is some simple things that could help this in really. Even something as simple as "last online #" could be a massive help. With raids and WT5 coming soon having a active and full clan could make or break your game play
