Other strengths and weaknesses:
- Good movement (climb and move distance).
- Huge aiming reticle - you can achieve any angle you want at any time.
- Pretty good gold-earning ability - lots of backshots, high angles, etc.
- Fun to use. Impresses people when you make nice shots.
- Low HP/Defense - Boomer can die in two duals vs many mobiles.
- Can be difficult to use - wind strongly (and strangely) affects your shot.
- No bunging ability to speak of - your shot doesn't disturb the enemy position.
- Boring because everyone else plays him.
