Battle roster ever gonna increase?

With 13 hero’s in game now and with Ludia forcing heroes on to us is there ever gonna be more slots in the battle roster??? I would really like at least 1 more slot.

I got bored of the same roster all the time, so I just switch out characters at the beginning of each session and treat it as a roster for that play time. I’d left Nayeli out for the longest time for PvP and am now having hilarious times when the Owl causes absolute havoc. The match becomes slapstick with all the misses.

Owl trinket is one of the only reasons I can beat people better geared than me. I want 2 more hero’s to be able to fit into roster.
