[HoTS]Baneling/Broodlord idea.

Broodlords are slow moving siege units, and banelings are suicidal AOE units capable of moving while burrowed.

My thought was burrowing a fair number of banelings (About the same amount as if you were going to bane rain), and setting them to follow the broodlords.

Thoughts? Opinions? Anyone else have interesting tactics for HoTS?
