I'm seeing SOME shadow blades show up as dodge or miss, but some are showing up as a melee swing. It's unusual and I'm probably gonna try a different approach to visualizing what's happening. That will take quite a bit of time though.
What I was doing for testing was popping shadow blades (and troll racial just for extra swings during that window), waiting 1 second, then turning on autoattack, then turning off the autoattack with 1 second left on shadow blades. That way there are no swings outside of shadow blades. Did it untalented and did not use any special attacks, nor did I use poisons.
