You should check out the Valheim Plus mod.

Removing crouch stamina drain (and in general rebalancing most other stamina drain) was the 1st thing I did.

I don't know what the devs are thinking with the current stamina balance.
It's like they have no respect for people's real-life time, and are balancing the game to play like an incredibly tedious mobile cow clicker, or freemium MMORPG.

There's one simple guiding rule on how to balance stamina:

Stamina should punish *mistakes* ONLY.
e.g. excessive jumping, excessive dodging, overly defensive combat, repeated missed attacks, etc.

Stamina should not get in the way of progression, nor should it get in the way of gameplay.
e.g. I should never be waiting for stamina to regenerate when I'm mining copper, chopping trees, exploring on foot, levelling ground, placing structures, etc etc.

I've only been playing Valheim a short time, and apparently stamina has only recently been nerfed into this atrocious state (though I've no idea how it was before the nerf).
Hopefully the devs realize their mistake, and take a different, more sensible approach to implementing stamina.

p.s.

There are tonnes of other QoL improvements in Valheim Plus, almost all of them enhance the game by alleviating the excessively tedious or repetitive aspects of the game.
