Suggestion for giving the LazerBlazer a purpose

Aaaaaaand LazerBlazers give juice to enemies.
One juices and kills everyone and everyting, second taunts in front of it, then vice-versa. Especially useful if the jackbots just died, each guy can juice two times before bots make it from the base.
Basically building LB's may be considered griefing because they give money and juice to the enemy team and occupy a friendly turret nub.
They could be useful though if there were specific nubs where exclusively LB's could be built. Or just replace them with another interesting and at least somehow useful turret.
