The WizKids blog has a new HeroClix strategy article looking at the interactions of the Lunge, Maneuver and Vault abilities.
From their website:
If I had to choose one feat that leads to players asking questions, Lunge would easily be in my top 5. Maneuver and Vault would probably make the top 20. Put them all together, play them on one figure, and you’ll probably spend half of your game explaining to your opponent just how things work. Feel free to bring this article with you so you only have to explain things once.
