Oh, I see what you mean.
I don't feel compelled to use "hide", personally. I only use it outside of combat (except for Rogue).
But it would indeed be nice to have "hide" as an action for everyone and as a bonus action when appropriate (Cunning action for Rogue, Goblin's Nimble escape, Ranger's Vanish at 14th).
RAW, "shove" should be an action as well, and "jump" only costs movement (not an action or bonus action).
Not that all homebrew rules are bad, but I don't see those ones as a logical improvement (especially not in terms of balance).
But I feel like this probably has been said multiple times on this forum already 😅
Yes. All these things would make the game better, but the stealth is definitely the most broken. It's gotta be fixed because dang. That's too easy. Everybody stealth, shoot, stealth. All enemies die.
Though I will say, I have done a Shove and Throw Enemies only playthrough up to the harpy fight, and my Barbarian solo'd all enemies using only throw and shove in every fight. No other companions. So that's dang broken too.
