Staff vs Wand and Focus

You’re not wrong. As far as I know, staffs are much worse than wane/focus. You can get the same mods that you could on a staff (gem levels up to 7, spell damage, etc) but a focus gives you extra ES and some really decent passive tree buffs (reduced curse effect, for instance). Maybe if they added some nice passive tree stuff for staffs like in POE1 (inc global defense, for example) staffs would be better.

At no point did any of the D4 sorc builds had a good staff lol

Staffs are awful, the massive stat loss is not enough to consider using them. I made it to about lvl 65 before being forced away from them as I was constantly under kitted. Source:made a coc comet build, it was bad.

The only reason to use a staff is either for its native skill (Pyrophyte for a living bomb build, Chiming for Sigil of power) or because it's a unique staff. Right now there's 0 incentive to not use a wand and focus, that may change in the future, but right now it's pretty much wand/focus always.

As a staff enjoyer, this is why you use staff: the price.
Get a great staff vs get an ok wand+focus. Just check the sum of stats you can get for your divs, and count that staff has +1 offensive rune slot. Also resists on focus are sketchy with weapon swap curses.

Yes, I do use a chiming staff swapping weapons to use the sigil of power. But I would like a staff powerful enough So i can fit my play style the best. Now, imagine Gandalf asking for a sec so he can swap to a wand mid battle. That shit it's hilarious to imagine. And that is kind of what happens in my mind. I do use wand and focus, but would like a staff play style.

The statistically better option is wand and focus, but it depends on the specific items. I'm running level 12 waystones with a frost staff because it has +5 cold spell level, and the wand I have is just +2. I could buy or craft a better wand and focus, but I'm having a good time for now.
