Stealing other class' abilities is a great way to throw in some already-tested mechanics as cool unique magic items. Warning for anyone trying it though, don't steal another character's thunder; if one player chose to be a battle master then don't give everyone else their cool abilities too!
Yeah, there's some abilities that are just a lot of fun to have, but if your party doesn't have the right class, they wouldn't get the fun. An example would be druid shapeshifting (especially for non combat purposes). That's really great for story potential, thanks to being able to use it for spying and finding routes.
