We always discuss who should be on what teams, and most of us agree that sometimes teams get ridiculous in size but equally ridiculous is the number of teams/books. It seems that back in the day there was the core team and then you had other supporting characters that helped out sometimes and appeared in some issues but were not always part of the core. Then all of a sudden we went thru a period where every mutant had to be on an team.
So in order to properly feature and develop characters as well as show their interaction with the team and what not, what should be the ideal size of an X-team? It could be a range or a specific size.
