LF are plainly annoying when you fight them (LOL LOL LOL, u no caz hitz meee!!!), and useless when they fight on your side. Having a LF on your team in a groupfight is like having -1 member on your team, plus 40 surprise bots for the enemy team because at some point the stray nuke -will- hit.
LFs are cool for racing.
And... that's it.
How to fix? I seriously have no idea because the concept "ultradodgy + small model" is a total fail approach in Disco.
