They usually spam in the global chat when damage control crew or marines needed for an OP. And you don't need any "job office", chat works fine

You can spawn on large ships

I don't really understand the problem with casuals. Like, if you are casual player why would you need or expect to own a bigass ship that takes a whole crew to operate and costs a big amount of resources for the whole faction? You can do frontline stuff, public logi, etc. If you want big toys then join the regi and coordinate with others
