The allure of Diablo barbarian classes was always simplicity.
In D4 barbarians are over geared, over complicated specialists for cooldowns and resource management.
Carrying around 3 more weapons than needed is the perfect metaphor for this class. It is innovation for the sake of innovation.
I duuno, feels like a pretty simple class, with the correct gear and aspects you don’t have to think about anything. Fury is always full and Fortify is always up and Berserk is always on, and vulnerability is always applied and you just autoattack all the time and throw in an ultimate every now and then and perhaps a core skill, even though they are useless now in S4.
Blizzard made Barbarians simpler than ever and simpler still in S5 by the looks of it. 
HoTa is going UP and UP in S5. Mark my words. If u liked WW/HoTa from season 2/3 it’s making a return with this Crown of Lucion. Finally big HoTas again… Let’s goooooo!!!
Same setup, Banished Lords/ red ring/ Grandfather… We gain 100x to this setup with Crown of Lucion… I’m excited as all hell
Lol if this still too complicated for you then maybe you’re the problem. Barbs are so easy to figure out and play
Op really a barb or troll?
If this class pains you just roll another class
Made me think.
