These are "main" events, which always have rank rewards associated with them. Ranked Events tend to be the longest type of event (3 - 7 days). There are always bonus/event units associated with ranking events, and often there are multiple packs, introduced over the course of any given event, which will include bonus units.
These events tend to be short (1 - 3 days), and are usually run concurrently with Ranked Events. While they have bonus units associated with them, they do not have rank rewards. Note that while historically, there may have been ranked instances, this is a list of CURRENT event types run without rankings.
Functional Events are ones that serve a specific purpose (such as to recruit or awaken units), or grant specific items. Functional events never have any ranking associated with them, and never have any bonus units associated with them.
