There isn't really much support for multiclass characters in the playtest; the closest being the Dual Path Mythic feat. However multiclssing is not required for that feat. Pathfinder itself does not really encourage multiclassing even though that is the only way to build certain character concepts.
In support of multiclass characters I propose the following Mythic feat: -
Multi-Path (Mythic)
You excel in many areas, allowing you to select abilities from several mythic paths.
Prerequisite: 1st mythic tier, Levels in 3 or more core classes.
Benefit: Select a number of mythic paths, including the path you selected at your moment of ascension (see page 3), up to the number of core classes that you have. You gain the 1st level ability of each path selected (archmage arcana, champion strike, divine surge, guardian’s call,marshal’s order, or trickster attack). The path you selected at ascension also gives other abilities such as bonus hp etc. as normal. Whenever you gain a path ability, you can select from list of abilities presented for all selected paths, as well as from the list of universal path abilities. You may also choose your trials from all those appropriate for all your selected paths as well as universal trials.
Special: Should you reach the 10th mythic tier you also gain the capstone ability of each path you have selected (true archmage, legendary champion, true defender, divine vessel, visionary commander, and/or supreme trickster).
Special: If you should acquire additional core classes after selecting this feat you may gain an additional path for each additional core class.
Also, I think the paths are broad enough to cover various kinds of builds, and the universal path abilities help round things out (especially with the one that allows the spellcasting boost). The paths aren't wedded to if you are a fighter, you must take champion; if you are a rogue, you must take trickster, etc. In fact I've wanted to see more people experiment with taking more out of the box paths anyway.
I really can't see any reason to allow someone past dual path -- the paths are broad enough to allow you to do a lot of different things, and going further I think allows for more potential for abuse and ability cherrypicking.
If you disagree Guardian, I'd be curious about the builds you are thinking of that would not work with only one or two paths.
I thought it obvious that you cannot select more paths than already exist, namely 6, so I did not see the need to explicitly state it. I will make the addition to the feat.
Here is the Mythic feat with the addition of the explicit limitation.

You may not select the same path more than once even if you have more core classes than there are paths.

That's not what I'm asking about. I'm asking about what class/level builds do you think would need such a feat to accurately reflect their concept?
I second the reasoning but strongly dislike the proposed fix. Mithyc is already broad enaugh to cover many different things, it's just that the scaling of many ability is either none like many martial bonuses or strongly tied into class level like spellcasting or supernatural abilities (like pally).
As of right now, the system as grown too much to be able to fix this, but for future materials (and even future edictions) i'd like to see less class-based scaling and more character level based scaling on many core abilities to allow diversity.

I agree with this generally. Because of class scaling, I think there are too many abilities that are ineffective or only minimally useful until you are very high level, and very high level games are few and far between.
That goes doubly for mythic--anything level based should be character level based. Perhaps even if multiclass casters can't get their caster level up in any other way, there could be a mythic ability that allows them to count their character level as class level, or at least something like add half their non caster levels to their caster level.
