The only thing you change about eating stamina only is, that you have a bigger empty stamina bar. My stamina bar is always nearly zero. It doesn't matter how big my bar is, as soon some stamina comes in, I consume it. Get the timings right of fights in which you can regen is the key.

The only thing makes a difference is the regen time. You have a potion in Mistlands for that. I tried it, but I personally feel nearly no difference with 25% more regen speed. Our archer on the other hand, used this potion with a lot of impact. I don't play with bow since a few 100 hours ago, so I don't know if this statement is true.

You can't regen stamina when using it, such as when trying to reach higher elevation to escape or for better positioning for the battle. You don't need any more health food than you need for parrying attacks. So you need to find the balance between the two, and there exists suitable options for that.

The stamina regen potion makes a difference over longer duration, as it lasts the same 10 min duration as the other "stat buffs" like resistances.
