As someone who kills and gets killed by this -blam!-, I can confirm that simply "moving to the side" doesn't cut it most of the time.
The amount of people I've poped from 90°around corners with this SoB is insane. I swear this thing has better tracking than Truth a lot of the time.
Heck, I still have the clip saved from when I was playing Comp and I shot it at a Hunter who had jumped off the map to avoid my buddy and I literally watched it stop midair and curve down to pop how ass.
"Simply moving to the side" as some people say really only works when you're closer to the Jötunn as it's being shot.
The tracking is actually better when the shot has some flight time to correct course. On those longer shots, you really need to jump out of the way or get behind cover.
It’s not consistent sometimes it tracks and others it doesn’t sometimes the burn kills and others you get a direct hit and they loose no health it’s working at intended just not consistent
