Simple Geometry Rework for next Update

This is the only achievement that I need but I can’t get it at all I understand how to get it but it’s just impossible the way it is. I would have a better chance if Blizzard could increase the damage to the storm arrows that’s the only way I can earn it. They could’ve just left it as it was in the past which was too get 2 killing blows (but obviously with scatter arrows) if they left the number of kills required as 2 then yeah I would’ve had it by now. So if Blizzard can do this one change for me that would be great because my head is hurting by the number of times I’ve been hitting it out of frustration. Just make this one change for me Blizzard I’m not asking for much. In addition this achievement may be easy for some but not for me I’ve been getting every achievement solo and I wanna keep it that way so if you’re going too boast or be rude then don’t respond.
