When I walked into Fallout 4 (first time round, I expected Bethesda to have learned everything from New Vegas), I assumed from Arthur Maxson being the Elder this time around (and that he legitimately said this anyways) that there would be an internal conflict between the Outcasts and the Lyons sides within the Brotherhood. If you're helping the Outcasts, you would've been able to use the Chain that Binds as a standing point to bring Maxson down.
It was disappointing to see the Brotherhood without any such conflict, especially when its clear Maxson is a hybrid of classic West Coast Brotherhood ideologies and the Lyons "for the people" ideology. There's no way he would've been able to avoid any internal conflicts in such the short time he took to become leader, especially when the Outcasts within the Brotherhood would've claimed that he was too young to lead.
Hilariously, it is also implied that Maxson is younger than the Sole Survivor, who I guess is canonically in his/her late 20s to mid 30s?
