That was my original thought to reduce Spirit to +1 to all skills, and is the best solution. Spirit needs a hefty nerf as it is so cheap and outclasses other items. Making it a range of +1-2 only leads to more frustration, which is not the goal. The goal is a well deserved nerf. Updated OP.
Keeping Grief in the broken state to keep melee semi-viable is a bandaid solution. The best approach to fix melee is to nerf Grief, and then follow up with implementing a massive patch to improve itemization, with special focus on buffing old school uniques. See thread below.
Sounds like a good idea to me, consistent mechanics. If Cold Mastery is nerfed to 1/5 penalty, then the developers should consider adding ability to pierce immunities the way Conviction and Lesser Resist does.
Just trying to have a healthy discussion with the community. No need for vitriol. Good day.
