Kinda makes me wonder how big the playerbase is on the Switch, compared to the other consoles? I play on Switch, and really enjoy this game! Probably one of my favorite games I've played in a while, just don't want it to die down on the Switch and leave me stranded, unless I want to play duos/squads with a random PC/Xbox/PS4 player. I suppose if this became an issue, Switch crossplay would probably be tweaked.
Switch playerbase is overall healthy, but as I mentioned in another reply, some regions simply don't have many Switches period (as in, there aren't even that many hardware units, let alone those playing Spellbreak). We're keeping an eye on that and may tweak things further on a per-region basis.
