Stamina is nice in the game but there are some things about it that i dont like: picking up gatherables use 2 stamina while jumping doesnt take up any stamina. Im not saying that you should make jumping use stamina because then you might get stuck but possibly make it so gathreables dont use stamina to pick up would be nice and also running is not viable because stamina doesnt regen by itself and running uses up so much stamina so i just dont think running is viable at all at the moment.

I was thinking about this while playing yesterday.

Jumping should definitely not use stamina, specifically for the reason of getting stuck. There were a few times I definitely got myself stuck in areas that I wouldn't have gotten out of if not for jumping (like the time I nearly stranded myself on the island you have to build a bridge to before I put the second bridge head down).

I do think gathering should use stamina - but maybe only at first. Perhaps as you level your gathering up the stamina used goes down? So at level 5 gathering it goes down to 1 stamina, at level 10 gathering you no longer use stamina.

Running using stamina makes sense; do you wanna get to the mines earlier in the day but have less stamina to spend, or vice versa?

It's come up in another thread here, but I think the argument boils down to: should stamina regen? I don't think it should, at least not without some fancy ring crafted at a high-level work station using rare components, but as came up in said other thread, we definitely need more stamina regen items, and early-game ones (such as apples) need to be easier to come by without expending more stamina to get them than they actually regenerate.
