And somehow I doubt you tried very hard to make your post readable.
well atm HS only gets 10% from diseases so with 2 disease up you would have 24% extra dmg instead of 20%, wich isnt realyl a big thing. however in 3,2 with the bloodstrike getting a 50% dmg increase the setbonus will shine. giving 120% extra dmg on bloodstrik with the 4pt8 bonus.
however somehow i doubt the 50% will last untill the release
