There are a few suggestions:
1. I would like to see the change as "damage per second" using item. For the calculations used: (speed of attack weapons + bonuses accelerate with items) * (mean minimum - the maximum damage weapons).
2. Create a feature called "total dominance", which will add up, how much in general, the first item better than another. What would be properly calculate superiority, let appoint summable attribute points. For example:
sp - (Summary Points)
10 ap = 1 sp
10 hp = 1 sp
0.05% critical chance = 1 sp
etc.

have 2 items:
1 (used):
+10 Stamina
+5 Strenght

2 (seen):
+11 Strenght
+6 Stamina
(+3 Summary points)
etc.

1. This dps value is not the same as how much dps you see on the meters, I don't see how this would be useful.

2. I like the current feature set of RatingBuster, and don't plan to add anymore bloat to it. For those not satisfied with the current features, I do plan to introduce more features as extra modules that you will be able to download separately. (e.g. RatingBusterPoints, RatingBusterAuras)
