Does one hand + shield even have an advantage over two hand weapons anymore?

Since now that the damage cap is 50 million (Not that I'd ever even hit 999999.) and there's now secondary weapons that can be used with two handers, I'm just curious if one handers even have an advantage anymore.

How close does the gap in damage range have to be in order for the Attack Speed from a one hander to be worth it?

It's supposed to balance out, with ~10% more speed for 1h vs ~10% higher weapon multiplier for 2h.
However, if you can reach speed cap with a 2h weapon (which is not that hard with decent SI, attack speed inner ability, or green MPE potions), 2h has a clear advantage.

Shields can be scrolled for attack, while other secondaries can't (but have some built-in). However, in this age of attack on every piece of gear + over 200 attack on your main weapon, an extra 20 attack on your shield vs. secondary is not going to make up for that 10% weapon multiplier difference.
