Wyvern Rend missing at close range

Playing through most of the campaign using Rend (Wyvern auto-attack), the buffed lightning version misses enemies a lot at very close range. This mainly happens to small enemies like Act 3 swamp mosquitoes and Act 2 beetles. Buffed Rend constantly misses any enemy slightly to the left or right of me. I need to keep turning around to swat one or two enemies at a time.

Same here, running maps, my accuracy tooltip says 100% chance to hit, yet I keep missing enemies with the empowered rend attack, sometimes I have to slash 2-3 times before I finally hit.

This is kind of annoying to play when you are surrounded by 20 monsters and half of them just don't get hit, even though you swipe right through them, then you get light stunned permanently from white mobs and just die.

A lot of the wyvern's attacks have issues with the attacks clearly visually hitting an enemy, but missing. Elevation also massively screws with it too.
