Ok... I'm thinking of something like this:
I'll make the equip gani so that the player lights the paper on fire and holds it ready to throw. If they don't throw it within five seconds, it will ignite in their hands doing damage.
Classes I think should get the Molotovs:
1. Grenader
2. Medic (these guys have no grenades. Let's be a little generous
)
3. Sapper
