Um your facts are false. Barbs are just the biggest, loudest community of them all so they actually ended up with the most changes out of everyone.
Patch 2.0.4 = Crusader, DH, Monk, WD, Wizard, and BARB changes
Patch 2.0.5 = Crusader, DH, Monk, WD, Wizard, and BARB changes
Patch 2.0.6 = Monk changes
Patch 2.1.0 = Crusader, DH, Monk, WD, Wizard, and BARB changes
Patch 2.1.1 = Crusader and WD changes
Patch 2.1.2 = DH, Monk, WD, Wizard, and BARB changes
Patch 2.2.0 = Crusader, DH, Monk, WD, Wizard, and BARB changes
Patch 2.2.1 = Monk, and BARB changes
Patch 2.3.0 = Crusader, DH, Monk, WD, Wizard, and BARB changes
Patch 2.4.0 = Crusader, DH, Monk, WD, Wizard, and BARB changes
Patch 2.4.1 = Crusader, DH, Monk, WD, Wizard, and BARB changes
Patch 2.4.2 = Crusader, DH, Monk, WD, Wizard, and BARB changes

Patch 2.5.0 = Crusader, DH, Monk, WD, Wizard and BARB changes
Patch 2.6.0 = Necro (newly added) no other specific class changes
Patch 2.6.1 = Necro, Crusader, Monk, WD, Wizard and BARB changes
Patch 2.5.0 = Crusader, DH, Monk, WD, Wizard and BARB changes
Patch 2.6.4 = Necro, Crusader, DH, Monk, WD, Wizard and BARB changes
Patch 2.6.5 = Necro, Crusader, DH, Monk, WD, Wizard and BARB changes
Patch 2.6.6 = Crafted Sets/Items for all class changes, and a specific BARB change Mortick’s Bracer’s.
Patch 2.6.7 = Crusader, Monk sets added and BARB changes
Patch 2.6.8 = WD, and Wizard class sets added and BARB changes again
We have a total of 22 patches listed on D3’s patch history website (Necro had 4 out of 8 patches) This is the TALLY of all classes and how many patches each class benefited from. I also added the % to equally add the necro into this statistic.
Based on the actual patch history since patch 2.0.4 it appears that Barbarians have been given WAY more attention and given more changes in more patches than any other class.
As you can see DH and Necro have received the least amount of attention based on patch history and instead of addressing this, blizzard doubled down with new sets for all classes and threw the most ignored classes to the very end.
