Notes

FAQ 

Why not Champion for 3.26 as a league starter?

I believe Champion is somewhat misleading as a league starter recommendation, while Slayer offers significantly higher damage output. 
To make fortification builds work effectively, you'll need costly unique items from trading, which won't be readily available or affordable early in the league. 
Additionally, you'll need to craft a chest piece with stun immunity because Unwavering Stance conflicts with Perseverance. 
In my opinion, suggesting Champion outperforms Slayer for league start (especially in the first few days) isn't accurate. 
A better approach would be starting with Slayer, then transitioning to Champion once you've acquired the high-value items needed to maximize its damage and defensive potential. 
Just expect to invest a substantial amount of currency.

Why not Axes or Maces or Swords, why Staves?

I'm not using Axes or Maces or Swords because I'm running Shockwave Support, which only works with Maces, Sceptres, and Staves. 
Out of those three weapon types, Staves are the clear winner since they allow me to scale Block for additional tankiness. 

Is the Stampede necessary? I'd rather move faster.

The Stampede is necessary because Cyclone of Tumult significantly reduces our movement speed, and these boots are the only effective way to counter that penalty.
If you prefer faster movement, you can certainly use regular Cyclone instead, but you'll sacrifice both damage and area of effect coverage.

What about the new Unique Starcaller?

Starcaller's physical DPS is too low for our purposes. It appears to be better suited for a Cast on Crit build.

LEVELING

In Act 1 use Spectral Throw with a physical 2H Axe until you get Sunder before Merveil. 
Use Sunder with a physical 2H Axe until Act 3 when we swap to Cyclone and General's Cry. Make sure you have a good physical DPS staff when you swap.
See the provided loadouts for gem suggestions and tree pathing.

REGEX

Vendors in Act 1/2: we mostly are looking for a G/G/R for Spectral Throw, a R/R/R for Sunder, a R/G for Leap Slam, as well as movement speed boots:
