Weapons like Exe Sword or 2H hammer have a sweep as every attack. Spear, as first attack, has a thrust. If you are surrounded or if you are into enemies’ range, you must push otherwise, during thrust attack, you can be hit. I haven’t said that you need stamina every single time, maybe you can have a smooth run where you never get surrounded… but I still think Spear uses more stamina than other weapons.
But mostly, to use stamina or not, it’s just a little thing (in fact, when I have made for you the post with stagger and armor damage value, I haven’t even written it).
The most important thing is that Spear must not nerfed because it has pro and cons toward other weapons and because it has a weak point: armor damage, wich is very low.
I have talked a lot about Halberd, but I admit that it’s a bad example… because Halberd, even if it still has a niche (as I have shown to you, its armor damage is higher), needs a buff.
But compared with 2H Hammer and Exe Sword, Spear has various cons. Both have much more damage toward armor. Hammer has more stagger (you can feel yourself better with Spear, but that Hammer has an high stagger value on every attack, while Spear only on 50% of its attacks, is a fact). Exe has more crowd damage.
Moreover if we nerf every weapon with stagger, the game will be very boring. Already now, playing with many heavy weapons (like Halberd or Elf Spear), seems like beating a wall with a spoon. It’s ridicolous the low stagger value of many 2H weapons.
We must start to buff the worse weapons, and then see the results.
