The -2 Max pipe-bombs out is a subtraction from the stock's 8 meaning you would have 6 max stickies and not 2. There seems to be an overly large amount of misunderstandings of this.

The instant arm time paired with low base damage would allow for mid-air sticky jump chaining with little to no risk of major health loss.

Also this weapons is designed to make sticky spam completely un-viable, seeing as the stickies will do little to no damage if detonated instantly. Provided the user plays demo in his intended class role of defense, the weapons power will show better as waiting about 10 seconds will result in the full power of the stickies.
