Raid finder vs duty finder

[Taika]

Never tried raid finder yet, can you just do it solo, as in cannot use it if with a friend?

You can queue alone or with a friend (or many friends). You can queue for practice phase 1, practice last phase or aim for clear. Other than that, it's not really different from Duty Finder. But the queues on my data center at least are really awful (even when queueing with 2 healers).
