for a zombie to be killed the brain has to be destroyed. i dont think a setting a zombie on fire is an effective way to accomplish this. also, what if the grenade does blow up the zombie. there might be a slight chance of his brain not being destroyed. and just because a zombie doesnt have legs doesnt mean he's no longer a threat.
and what about the slight chance that the grenade blows the zombie head off, then you have a flying, biting zombie head to worry about.
also!!
different things to consider when chosing weapons. flame throwers use fuel. what happens when that fuel runs out?
what happens when your idiot friend sets the place on fire? now you have to face the hordes as well as an out of control blaze.
these are things to consider. The upside is that flaming zombies might act as a beacon for any rescue attempts.
