On Grief (And weapons)
There’s a simpler fix to Greif. Make it not apply to primary attacks only, and leave it on (or add it to) skills such as smite, or blade fury, Warcry, or Leap (no, not leap attack, the pushback on landing portion of leap doing damage would be hillarious to have a spec around to be built), or mindblast, or psychic hammer.
This gives it niche spots in builds, making them viable, because other specs that use it have viable alternative options between Last wish, Breath of the dying, Phoenix, and Stormlash. There are many endgame viable weapons for many classes. I don’t think focusing on them is necessarily productive beyond making something More Niche to make other options considered.
On Shields (not just Spirit!)
Spirit is perfectly fine. The issue with balance changing this runeword or nerfing it is irregardless of if you drop it to +1 skills, you still don’t have options to beat +35 FCR & 112 mana on top of resistances.
If people want spirit to be balanced, Stormshield needs to be brought up to par, in addition to Lidless wall and Vesertaunt. The ward too. There are so many great thematic shields, but those are shields, spirit is an offhand. That said, pali shields have the right idea. (Exile, HoZ, alma negra are endgame viable alternatives till a more focused option is available to your character.)
Phoenix is the elephant in the room, and needs to be balanced to be honest, partly because of how %Enhanced damage offhands calculated damage in this game in some instances. On shields, it should be limited to 300-350% ED IMO, to give DW Claws a chance, and other offensive shields / weapons a chance to catch up.
However, if we’re talking pure power curve, there are two endgame viable shields, unless Niche spec’d, (yes, looking at smiter!) This needs to change.
Enigma is a quintessential example of an endgame item. there are 4-5 chests in the game that are considered Endgame for characters: Enigma, COH, Fortitude, Arkaines (BC +2 skills) and Skullders (MF is why). 4-5 because 1 or two of these is debatable (Arkaines / Skullders)
If you are looking for alternate options or suggesting buffs for Endgame items when there are 4 options, the two rarest armors in the game should be buffed; Tyreals (which everyone can agree with, it’s a trophy, not a good item), and Templar’s might. That would bring it to 6 chest pieces endgame, if these were being adjusted, and make them more than ‘eyecandy trophies.’
So if we’re going to say something is op or not op, how about we point out that there are only 4 good rings with 2 ring slots (SOJ, BK, Ravenfrost, and Wisp; Nagel honorable mention), or 3 good amulets in the game (Maras, Highlords, and Tal’s; Metalgrind is bad and painful as a sacrifice), or 2-3 headpieces in game (Shako & CoA, now 3 with flickering flame, wisdom is meh, and doesn’t affect blade fury; this is bad.)
There is more to balance than just, ‘these 3 items are OP.’
Rather than just calling for nerfs, consider how it impacts the game, the metas, diversity gearing options, and how it can improve the game, and make it so items are better targeted than just ‘too powerful.’
Lets also be clear about something else regarding balance. In order for there to be ‘good items’, there has to be Bad items. I’m not saying buff all items to tuesday. But I am saying that D3 almost got it right with ‘these are options, but these 1 or two are the best’
Also, like HerpSquirter said, not nessasarily the right time and place.
