Nova’s with the ‘tracking’ ability (Top Tree) dont track based on line of sight, but by some magical entity that can see through walls. This sounds good, until you throw 10 nova’s at enemies, which should easily kill them, only for it to home into the wall, making it useless. This is especially apparent in crucible. This can be easily fixed though, just make it work off line of sight, rather than player positions compared to it.
