The TLDR 2H Barb

[kurs_x5]

Which is the order of skills to put the points?

I've been playing around with the build, made it to scosglen on ssf run.
With max immortal and weapon RW, this totals 55% dodge, which is pretty high, paired with our huge defense (effortless 1.5m thanks to shield).

Isn't Immortal avoid working only when you're standing still?

You have to stand still to deliver damage.

Looking at patch notes, finally a lot of changes for earthshaker tree:

► Show Spoiler

Earthquake: weapon damage is now 80%/200%, up from 70%/140%
Shower of Rocks:
Rewrote the entire skill mechanics from the ground up
Will no longer do extra 20 hits per cast that don't carry any weapon damage modifiers (WPD bonus%, deadly strike etc.)
Visuals no longer exist on the server, improving performance
Reduced delay between rocks by 25%, as a result damage per attack has increased by 29%
Fixed tooltip error regarding physical resist reduction (claimed: 5%, actual: 10%)
Tectonics: has received a major overhaul
Removed scaling chance to proc Shower of Rocks
Shower of Rocks proc is now always 100%, with a reduced duration, as long as you have enough Power
Power is gained based on your total Strength and Weapon Physical Damage bonuses
When maxed, grants 1 power per 100 Strength and 1 power per 10% Weapon Physical Damage bonuses
If you have less than 60 power then the skill has no effect
With 60 power: trigger a Shower of Rocks with 12% of the original duration on every Earthquake
With 140 power: trigger a Shower of Rocks with 25% of the original duration on every Earthquake
Tectonics procs will now spawn in front of your character instead of on top of them for better coverage
Fixed a bug where sometimes the skill would do no damage or have no visuals
Aftermath:
Now requires Heart of Stone
Tooltip now shows magic damage gained
Heart of Stone: Crushing Blow doubled, Attack Rating increased by 50%

As far as Earthquake goes, significant buff, not sure if it needed it, it will be absolute steamroll for leveling with 200% aftershocks being spammed, from level 2. Heart of stone. AR bonus will be noticeable, crushing blow was high enough, shouldn't feel much different.
Main thing is SOR changes, and it is difficult to tell how it will perform without trying. From description it seems like it was adding lot of extra hits that were unaffected by damage modifiers, so removal of that, is compensated by reduced delay. Does this change makes it stronger or weaker in the end, hard to tell.
As for tectonics, instead of getting inconsistent proc chance, we get consistent procs (always), but weaker (short duration sor), but also scalable by strength and ewd, kind of double dip synergy, as these stats both add damage and with tectonics will also increase duration of procs. There is also new mechanic, that causes it to spawn on top of target, not our character, which could be fairly significant, depending how sor procs centered on barb were really hurting the dps, and "real life" dps where mobs are moving around.

Overall this looks fairly interesting, and should be stronger than before, also stronger in QOL sense, as procs will be more consistent, so aside from raw numerical power, build should feel better to play.

I ran this couple of patches ago with 1h, as 1h+shield was buffed some time ago to be 6fpa, and this helped to proc tectonics. Now with tectonics being 100% chance, there is no downside of using it with slower 2h axe. However problem still remains, shields are good, tons of defense, useful stats, there is

Weapon Physical Damage +(60 to 80)%
+(81 to 100) to Strength
+(225 to 250) to Dexterity
5% Chance to Avoid Damage

really cheap high runeword, makes it difficult to compete for 2-handers.
I'd still do conquest helm + immortal combo to run over 50% avoid while standing still.
Angelic items could change things, depending how realistic it is to get good one, high new affix rolls, could be competitive to runewords.
