When guild is low level it's pretty easy
I maintained a level 20 guild entirely solo for quite a while
Only takes a concentrated group effort when you level the guild up more
If there's not many active players in your guild, let it drop a few levels and the requirement will go down significantly
There's a calculator on my site that shows you exactly how many points needed per day based on level and members, have a look and you'll see. What level is your guild at the moment and how many members are there?
