On average a 10 man guild would require ~3 pulls to kill the boss. A 25 man guild would then require ~15 pulls, 5 times as much. It gets much worse with harder mechanics. Let's say there's one where you can fuck it up 20% of the time, a 10 man guild would require 10 pulls, a 25 man guild... 265 pulls.
