This table is incorrect.Jess said:
MoM1+WP1 = 3.071% damage increase, not 2.9
MoM4+WP4 = 21.4895% damage increase, not 20.0
The one who made this table didn't take into account that higher base damage means higher critical hits and thus more gain from WP. As a result all the numbers with WP are lower than they should be (except when WP is the only RA). At least if he consitently used the formula he used in the two examples I checked.
