Highly encourage people to try this, if only for kicks. As long as you have a couple bodyguard units to draw arrow fire, and keep the hounds tightly clustered (set them on top of each other), it's incredibly powerful.
Of course, there's not a lot of micro involved, since the hounds go berserk immediately. But it's a helluva lot of fun to watch. You've got this massive ball of raging giants bouncing from one unit to the next (instantly cause a rout in most cases)
And given that it takes a mere 1 round temple to build hounds, you can build them up quickly (and retrain them at the warfront very easily).
