So I'm not sure if this has been discussed before...but I found something interesting about a superior weapon mod (+attacks per second mod). Not sure if this also goes with other superior weapon mods..haven't had any to really test. I posted about it in the Battle.net forums but just wanted to see what people think.
Basically, if you have a superior weapon with +attacks per second it also gets applied to your other weapon as well. So in my example that I posted on the official forums I had a sickle that had 1.3 aps and a superior sabre with 1.59aps(+.19aps mod). When looking and the dual wield aps it didn't make sense to me (I know it shows your next weapons aps but even so it wasn't correct after factoring in the dual wield 15% buff). So my sickle instead of just having 1.3x1.15 aps it gets (1.3+.19)*1.15 aps. This makes it much stronger than before.
What made me wonder about it in the first place was that replacing the 11.9 dps sabre with a 13 dps weapon actually lowered my dps and that is what got me to test and figure this out.
Has anyone else noticed this behavior? I believe it would double dip is you had two superior sabres but I haven't had a chance to test that yet. This could make superior weapons quite good.
