Alright, I'm not gunna claim heavy aim doesn't exist again. I have felt it recently and the fact that the pros complained about it at worlds is pretty bad. I was wrong to say it was just placebo.
That said, this new modded controller thing isn't proof of anything. First of all we're pretty sure heavy aim is input lag, this shows an inconsistent distance in which the reticule moves. To use something I posted on Beyond:
If you hold a button for 50ms the game is always going to receive an input which lasts 50ms, regardless of whether you have 0ms or 100ms of input lag. The difference is how long it takes for that input to be displayed on the screen. Input lag won't cause an inconsistency if the amount of time a button is pressed is always constant.
Let's say that the reticule moves 45 degrees if you hold the stick for 50ms. Assuming the controller always rumbles for 50ms (which isn't something we should assume and the reason this doesn't prove all that much), the reticule will always move 45 degrees, regardless of how much input lag there is.
If this is caused by heavy aim it shows that heavy aim is not input lag, which is weird because that's exactly what heavy aim seems to be.
Secondly, this could be just as likely proving that H5 doesn't always use the same rumble pattern. Especially when you consider that it seems to always jump to one of three spots. With a random change you'd see more variance. Until we can prove that H5 always uses the same rumble pattern this doesn't prove much.
