This is the reason i'm still using freakin' frostnir. 12 stamina vs 16, 2 handed costing like 20+, is a big difference. Max stamina should increase stamina regen, heck if i have to say Skyrim did it better, than you know the stamina system in this game kinda sucks.

How did Skyrim do it?, base % of your max stamina, then extra stamina regen improves the base percentage. So 5% per second + 100% extra regen = 10% per second. The higher the max stamina, the higher the number per second. Best of both, it feels balanced early on and you don't feel like an old man trying out cardio later in the game.

Just imagine, 2 biomes from now, 1h weapons will cost 20, stamina food is higher but the regen is still the same, that means what, we can block a few times and 1 combo of attacks and then have to wait 15 seconds for it to regen back? Either do it like i suggested or remove the increase in stamina usage for weapons. Better stamina food should mean more attacks, not less or the same with more intervals in between combo's.
