the original model when it was 5 figures was supposedly , hero and one of their main villains.2 second stringers and a fan favorite.
wave one
Batman /penguin
Orion/red tornado
Etrigan

Wave 2
Aquaman/manta
firestorm/ b&r supes.
Harlequin

Wave 3
Hal/ Sinestro
Robin/ Deathstroke
nightwing
and so on and so on.
but the 7 to a wave. is just a terrible assortment number, its there to allow Mattel to push older product out with new stuff and usually what the call all stars which we call peg warmers.

7 figs in a wave is terrible in my humble, it means they break up the wave, so it becomes more difficult to find the whole wave and build the C&C and it means we get unwanted figures clogging the pegs at retail
they say these "allstars" are for the kiddies and mothers who will recognize the character and buy said fig for Junior. I call shenanigans, no mother on earth is buying a 15 dollar figure for the kid, heck if I was a kid I would buy 3 joes for what one DCUC fig costs! ata least at that price range I could Army Build.

and when we finally complain or ask them why we cant find any figures (usually because the retailer is choking on unwanted old stock) we get the answer of , oh well it is a collectors line.... Ugh.
