Not Bug arrow bomb doing a wrong damage , I guess

nothing has change of my equip between new source and old one, but arrow bomb doing a lot more damage then before.
normally , it should doing damage like this: first mob (700) > second(1500)> third (2000)>....... six(5000) (the more mob you hit, the more damage you do)
but now it doing damage like this: first mob(5000) > second (4000)> third (4000)> ......six(4000) (the damage is no meter with the mob you hit)

is this a bug, or a buff?

 

nah it was supposed to be 50% damage on the first mob and 130% on the rest. Later versions fixed it to 130% on all (v86 also buffed it from 130% to 150%).
I think they changed it here to be like the newer version maybe (it was like that in beta too)

 

Thank you
So inferno is become more useless then before

 

Inferno got a big buff in v86 too (it could burn enemies for extra damage ) but here it doesn't seem to get buffed
