Before you all say "This isn't COD," flamethrowers were used allot in real life Stalingrad and were a useful weapon. If you allow 1 per team and limited mobility along with a big puff around him when he explodes, killing nearby allies, it would be more fair and equal it out. It would be a useful weapon In clearing a house but not for storming at open areas due to his slower speed and short distance gun. This would own in my opinion
