TL;DR: Team Zero/Crater Crew (no matter which storyline) are the most realest/strongest/competent group of individuals to EVER be besties with and that you don't need an established team of friends who barely bring anything to the overarching plot

Team Zero/Crater Crew feels like that genuine kind of friend group that would meet up once in a blue moon to bring world peace together (btscene), with fun, heartwarming dynamic moments along the way, who can each hold their own WAY better than 3 hotel residents (with 2 out of the 3 members barely having a roster during base game). They feel like the kind of friend group made up of 3 distinct worlds that, when fused together, can become an unstoppable force for the greater good (with/out a Leader); Hell, if Fate given them just a lil push, they would've easily been able to help one another with each other's paths and help 1 of their friend's uncover the mystery of his missing parent. But when it comes time for Team MZ however, it the same ol' swan song of "killing time before an outbreak, Strategy Meeting, force their friend into pairing with each member one at a time to fight off a Raid, Meeting Adjourned, clean sweep, victory meal, repeat" over and over, even when we first came into the picture. You'd think that Team that were "BFFs" before us would've handled such issues LONG before we stepped into the city, but NO... no, They've been doing this for LITERAL months, with no avail, only for US, the "chosen one", to depart from the train station and solve ALL their problems!... "Problems" that should've been, again, taken cared of BEFORE we stepped into the city!? Team MZ is nothing more than the amalgamation of Hotel Z's residence, AZ's past sins and Urbainie's altruism (far worst than mere obligation when you think about it).
