lemme rephrase this
when you first fire the rocket initially it's traveling in the exact direction you want it to go
while it's IN THE AIR, it will randomly redirect itself- the longer distance between you and the target the more potential for out-of-control spread, so you want to put as little room as possible between you and the guy you're trying to smack in the face with a rocket without you getting hit
assume it's a gamble unless you're like, just out of the blast radius of your target
