>S0 Mini Battle Pass Wakanda theme
>One tank, one support, three DPS
>legendaries for Panther and Mantis, the latter of which has nothing to do with Wakanda

>S1 Battle Pass Vampire theme
>Two tanks, three supports, five DPS
>legendaries are Loki and Wolverine, neither has any connections to vampires

>S2 Battle Pass Krakoa theme
>Two tanks, two supports, six DPS,
>legendaries are Spidey and CnD, both non mutants

Highly likely the next season is symbiote themed and the remaining characters without Battle Pass skins are:
>Venom
>Thor
>Groot
>Emma
>Thing (F4)
>Mr Fantastic (F4)
>Human Torch (F4)
>Storm
>Hawkeye
>Star Lord
>Winter Soldier
>Ultron
>Jeff
>Invisible Woman (F4)

So my prediction for the S3 BP roster is everyone remaining except the F4, because you either do all together or none, and the remaining non-F4 round up to a perfect 10.
Also the last four BP legendaries have all been both DPS and supports.

Or I'm just completely wrong about everything.
