If you've payed attention to any of the ESO videos, you will notice that the players are always duel wielding. At least when not using magic or a 2 handed weapon. Does this mean there's no place for single handed combat in ESO? In real life, duel wielding has massive down sides and requires far more skill then using a single sword, like you can not swing with as much power as you could if you griped your sword with both hands.
I much prefer single sword style over duel wielding, but it looks like I'd be at a massive disadvantage in ESO because it would essentially be playing with one arm tied behind my back.
Also, it looks a bit jarring when you have an entire army of people duel wielding, as it's an uncommon style.
