However, the reality of a large guild looks more like:
20 active members who produce ~4,000 renown a day for a total of 80,000.
50 members who are somewhat active producing 1,000 renown on average a day for a total of 50,000.
30 members who are inactive and produce very little (say an average of only 500 a day) for a total of 15,000.
Come level 82 the guild would suffer 145561 renown which they cannot overcome.
