4812622Iron Bomber is a straight downgrade - worse rollers, no upside.
Incorrect. It gives the Demo reliable quick and short lived area control. As the balls don't roll, you know exactly where they are going to land, and going to explode. They can be used for quickly causing damage or area denial to certain places, like a doorway, choke, or control point much like the GL, but when you spam pills at a control point, you don't really know what you'll hit because they may simply roll away...but with the Iron Bomber you know almost exactly where they will detonate. That's a huge upside, especially for high level play, and is equalized by the slight decrease in damage.
The Iron Bomber is probably one of the most balanced weapons Valve has put out in years and I feel its perfect for comp.
