I'm saying this on behalf of Marvel in my opinion.

Please, please, PLEASE give them the chance to do the Police / Mercenary trio of Piltover.

Mostly looking at Camille, as this dark hero-esqe champion NEEDS a full comic to herself besides her release comic.

On the other hand, besides this; will Riot be allowing Marvel to touch some skin lore? Some skins could definitely use a universe expand and now could be the time to do it; like Dragon World and Omega Squad. It would be breathtaking seeing Pantheon or Teemo's story unfold in a comic. Even a better time to have Marvel and Riot expand Zombies / Slayers universe as well!
