I really like the idea that classes are designed around some kind of lore factor, unfortunately the idea of Lore is that it's subjective. In some cases people believe Fury should be a blood crazed lunatic swinging wildly with zero fucks given, however some believe it's all an act and the 'berserker' is actually a smart guy.
Some believe Arms should be about tactic attacks, making little dents in the armour and then delivering attacks to that specific point, others believe it should be about out-lasting your enemy with small attacks and bleeds and what not whilst another group of people think it should be about hitting the living fuck out of the target so hard their ancestors cringe.
In 'real lore', if that's even a thing... Most Warriors had shields. That's probably why after 10 years we finally get Gladiator Stance.
At the end of the day, a lot of us appreciate a good Warrior story or a bit of Warrior lore (not rp kthx), I know when I read the Barbarian story on the Diablo website I instantly wanted to play a Barbarian... Shortly after re-rolling to Wizard because I couldn't get any fucking loot. My point is, it's all good and dandy to use your opinion to show what Fury should be like but at the end of the day Class Design should come before anything else... As much as I dislike it.
