I've tried it.

I've found that it not only robs you of your balance and leverage it also steals an opportunity for work from you.

When you lunge you lose the ability to apply full power and precision. You're not grounded, losing you're capacity for power.
However, lunging means you're also going to be moving towards an opponent at a fast rate. Even if you do connect you're bound to be two close to capitalise, smothering your own work and wasting opportunity.
