This is indeed a big change in balance with shove available as a bonus action Oo Especially with a fixed value for Sleep HP.
It would be better most of the time, in my opinion, if we could simply roll for sleep HP instead of having it assigned as a fixed value. Same with point assign at character creation. Let us roll our characters damn it.
I think rolling for Sleep HP might be difficult from a technical aspect. But that would be nice if they find a way to implement that in a way that's fun.
Having Shove as an action seems like an easier fix.
Rolling for stats will most likely be possible according to that
post and that
article. Maybe a feature for the full release?
