Well, an update has been put into place has changed the magical drop % to be lower, and have a lesser drop chance. this makes things less over powered.
New magical drop system is like this.
Elite: 5% chance drop
1% - 37%
Heroic: 0.5% chance drop
37% - 75%
Epic: 0.05% chance drop
75% - 112%
Legendary: 0.001% chance drop
112% - 150%
Also, the duel wielding system works like this.
If you equipt 2 of the same weapon the only bonus is that your skills raise 50% faster, however no attack speed or power is applied.
Duel wielding does not attack with both weapons at once, instead it alternates hands each time for example. Attacks with left hand, then right hand, then left hand, then right hand.
This is good if you want to train 2 different weapon skills at once, or if you have 2 different weapons with different secondary effects for example.
In your left hand you have a Sword, and in your right hand you have an axe.
This set up will raid sword and axe skills, as well as when attacking you have a 20% chance to double attack and your attacks have Aoe.
