Fucking hell i wanted to play this mode daily:/ my dream addition was a coop mode and that seems to be limited.
I can play ranked mode and turf war whenever i like why can't i play this whenever i like?
I can guess there might be several reasons. Keep in mind too that these times very likely could change. Every other day might be temporary.
There is gear that you can only get from Salmon Run. We don't know the drop rates for this yet. So they might be trying to address that .
They likely don't want people overloading it since it's a new mode.
They said the mode would be getting new content and changing. Maybe they're still looking at feedback early on and want time to look at it and readjust things. With it being offline every other day gives them that time I think.
Or they simply want to force variety. They don't want you playing any one mode exclusively outside of Turf War. It's why SplatZones, Rainmaker, and Towers are in a rotation.
