The only way i see this happening is if the char have animations for it..
as for main and offhand, thats same as right or left hand..
Dual wielding again if char has animations for holding something with 2 hands.
I'm sure if u make your own chars, you would do your own animations for weapons..
I'm not sure on the pre-build char system on what they have.
maybe an Alpha tester could answer this.
Are the weapons and armor stats going to be static like WOW,
or can we have it like Diablo 3.
Were the server gen random stats base type and char u are
Or can we do both?
