If necessary, however I think that every squad currently at the limit of 13 has players that never show and can be inactivated. It shouldn't be necessary to raise the limit.
On EG: P, x-wing (0 min combined pt)
On Mello: jedi master, FroBlock (5.6 min combined pt)
Hooligans doesn't have any extremely low pt players active but they also have 14 people who have recorded pt this season. If some of those players aren't showing recently and turtle feels the need to recruit more he can inactivate people.
