Which launchers do you prefer to use right now?
Personally I will use the RPG as a default option because it has a better burst potential than the recoiless and a bit better blast radius. It can also lock on to designated targets like the recoiless.
If I want to focus specifically for vehicles I will use the Lissile because it has the flexibility of being able to be piloted towards both ground and air targets.
While I have retired the recoiless, I know at least one person who is really good at nailing annoying helicopters with it.
While I love the romance of the Javelin, I just do not find enough people who designate targets so that I can take advantage of its more fun Top-Down mode.
The Javelin has so much potential vs camping snipers as well if another player decides to be a good bro and uses the tracer dart either on a sniper directly or on the terrain very close to them.
