As has been discussed elsewhere, many think that that's an overly-harsh penalty on flame weapons
ROFL! Others think the double up rule is too much!
Think of it this way - when you're submerged in a vat of boiling oil, would you be any less screwed if someone where to throw another boiling vat of oil on you? No. There's only so much cooking you can do 
Artillery explosions are a different kettle(vat??
) of fish. Explosives tend to have expanding shock waves that expand and can overlap - carrying shrapnel with them. Detonate an explosion on your left side and you get hit by shrapnel from the left. Drop another on your right at the same time and you get hit from both sides simultaneously meaning twice as much damage simultaneously.
Look I know we hate to bring realism into gaming but it just makes sense - well at least to me....
