I'm going dual wield nightelf arms warrior as my first HC char. What difficulties am I in for ?

I min maxed the heck out of classic woe launch and havent really been back since phase 2 or so. I know warrior is supposed to suck and everyone screeches dual wielding while leveling is miss miss miss but idc anymore. Yolo. I wanna slice and dice (no rogue) enemies and see lots of numbers. That said, what challenges will I face ? What are your best tips ? I've literally NEVER played a warrior in my wow history.
