There should be reforging.
The Devs repeatedly fail to properly balance secondary stats for all specs. (Just look how crit is basically worth as much as Int for Fire Mages, how could they let that go live?)
This is our way to help mitigate the damage from their failure.
Stacking one stat is not an optimal strategy, due to soft caps. For instance some classes might need only 20% haste. So if someone wants to stack one stat - more "power" to them.
There will be less useless gear as there will be less useless secondary stat combinations (none at all). There's gear with only ONE secondary stat right NOW in the game.
If there are only 3 secondary stats: Crit, Haste and Mastery. It means only 3 gear options per slot. And 2 of these 3 stats are GOOD for any class. So you only skip ONE of the options. 33% useless gear ONLY. But the rest is BIS. And that's not accounting for off-specs that might need that useless gear.
Unlike now - few bis pieces, some OK pieces and the rest - ilvl boosters.
All right, gentleperchildren, let's review. The year is 2024 - that's two-zero-two-four, as in the 21st Century's perfect vision - and I am sorry to say the world has become a pussy-whipped, Brady Bunch version of itself, run by a bunch of still-masked clots ridden infertile senile sissies who want the Last Ukrainian to die so they can get on with the War on China, with some middle-eastern genocide on the side
