There should be like daily clan achievements which give xp depending on how hard the achievement was, like 1 achievements each day and if a clan is not able to do it then it will stop at 3 ahievements till you finish one and being able to replace one with another if its too hard to do

It could be like
Do 5 clan wars
Do 3 clan wars
Win 5 clan wars
And maybe to change some stuff up then like
Do 5 clan wars in lenshu
Win 2 clan wars in judofrac
Do first to 20 wars

That could just change some stuff in wars which will be great
