If you are going to nerf stamina (which will negatively effect light armor users much more than nerfing the 200 con attribute perk by a mere 10%) then you ought to lower the cost of blocking with weapon to add more incentive for people to use a great pvp mechanic rarely ever used. This will make combat more diverse and skill based by adding or offering a more useful mechanic to survive if we can barely if at all kite.
I despise the idea of nerfing stamina but I would feel better if you buffed blocking stamina (with weapons) in return and I think many would be appeased.
