They probably need to make spiked shield do d4 piercing damage, rather than d6, and 1 AC rather than 2 if you use it to attack (since you're not using it exclusively for defense any more). I'd be cool to get a +1 bonus to AC while dual wielding by default, in exchange for -2 / -2 to hit. And egads, let people wield a longsword + shortsword without a feat, and with a feat let dual longswords be ok. With bounded accuracy, I see -2 to hit on all your attacks could be quite a penalty. That has to be reduced with the Greater Two weapon fighting. Don't like the idea of getting advantage. Why? I already have "advantage" by virtue of getting two dice rolls, two independent chances to hit, rather than one.
I thought the greatest DPR was going to be 2 handed weapons? Via Deadly Strike scaling W damage with level? That extra DPR should add up, especially after level 6 when you get multiple attacks. There should be good in-game reasons to use multiple weapons, such as benefiting from both properties and putting in some use for those offhand light magic items that would otherwise get ignored or end up as shop fodder.
