Is this a desktop-only solution, i.e. no mobile? Then it is bound to be a no-go for most users. My checklist is pretty short:
1. Clients available on web and/or all platforms, must be able to add/copy to clipboard passwords on all platforms.
2. Synced or Shared database between all clients.
3. No subscription cost (upfront cost OK).
Nice-to-have things would be browser plugins, command line interface etc., but that isn't essential.
It has mobile counterparts. The copy/paste part is Ok, the syncing depends on the clients. I think syncing is always through some other service, some apps claim a nice integration with dropbox, some are more tedious (I use miniKeePass on iOS and it's not fun to sync), but you won't have any fees other that what you pay for dropbox or some other third party storage.
Overall keepass is far from perfect and lacks polish, but it's good enough for most purposes, and doesn't require an internet connection, which opens more use cases (keeping banking info or wifi passwords for instance)
