25 person max raid size for expansion

[Skandranon]

And I can make the argument "the more constraints, the greater chance that someone makes an issue of it". Because that is demonstrably true. Given that an average person will 'make an issue of' a given constraint 1% of the time, given only one constraint the odds of at least one problem are as follows:

You can't express the probability that someone will make an issue of something as a percentage. Some people will make an issue of everything: some people will never make an issue of anything. And you can't make the average argument because guilds are self-selecting: they can choose people who generally don't make a fuss (and people that do will generally find themselves out of the raiding population one way or another).
