Vulpera.
Let’s get real here. Nobody’s playin Ally in 8.3.
Worgen by far looks the coolest for warriors on the alliance.
Apart from human, I’d probably say Nightelves. I don’t know, the lore & whatnot in Legion’s storyline in Val’Sharah at Blackrook hold gave me major Night-elf warrior vibes.
Honestly, Gnomes. Sure Humans look Heroic, and Dwarves have a Warrior culture, but when you see a Fury gnome with twin Ashcandies you know you got hit by a tiny ball of doom.
p.s. Ashkandi, Greatsword of the Brotherhood ((https://classic.wowhead.com/item=19364/ashkandi-greatsword-of-the-brotherhood))
funny… 
Seriously Pandas aren’t great as much besides Monks and Rogues.
Feast your eyes
Once I roll my Mechagnome, I’m race Changing Mary Blood Elf.
Kul Tirans, obviously.
Gnome warriors are the best warriors atm, maybe because all their blows are low blows.
