please use a different colour, it hurts my eyes
the grenade launcher here doesn't explode on contact, so you would be able to run away fast, or take him out before you die, your choice.
and as i have said before, it's usefull, not just for easy kills. if there are some people who keep rushing(i heard SD doesn't like the tank+medic rush strategy) in a group, you could take them out using your grenade launcher.
if someone is camping, be it with or without wallhack, you can take him out to get him out of the spot.
ofcourse it often gets abused, but is that the fault of the dev's? as for not making it ohk. a grenade launcher usually has an even smaller firerate than a sniper rifle, no-one would use it since apart from softening them up, it doesn't do anything except getting you killed
