A shield can potentially have WA scrolled onto it and chaos-ed, while a Rosary will only have specific stats. At the upper funding limit, that's about 20WA difference, but then again 2H weapons have a slight WA advantage, so that goes down to about 10WA difference (to the advantage of a 1H+shield).

The 2H multiplier is 10% greater than a 1H. With an equal amount of WA, you will ALWAYS do 10% more damage with a 2H than 1H per attack.

don't forget that at the upper funding limit, 2handers can also get a few extra attack due to getting to new enhance tiers faster. so the attack difference between a scrolled shield and a rosary is indeed quite small usually.
