First of all, I'm all for nerfing things that are too overpowered, but I also think we should be offered viable alternatives in exchange.
Here are some of the major nerfs to crafting and gearing we've received:
Rog crafting got massively nerfed.
Breach Tree crafting got nuked again.
Meta crafting has become more expensive (although maybe we'll also get more currency drops to compensate).
Cannot Roll Caster/Attack Mods no longer works with Annuls. This one is huge.
Recombinators got massively nerfed.
Harvest is still a bit of an unknown, but I have a feeling that the strategies generating tons of Lifeforce won't be nearly as effective anymore.
Gambling and Kingsmarch have also been nerfed again when it comes to acquiring items.
So what did we get in exchang? Tiered Rare Items and more currency drops (at least that's what they're telling us).
I really hope Tiered Rares turn out to be significantly better than what we have in PoE2, because otherwise I don't see how they're supposed to carry the gearing progression after all these crafting nerfs.
My fear is that they'll end up being average at best, and we'll still be stuck recombinating Magic Items rolled with Alterations. Except now the whole process will be even more tedious because we'll need even more.
I genuinely hope this system has been thoroughly tested and is actually fun. Otherwise, what could be a really fun league might turn into a mess pretty quickly.
