Stacking 4 or 5 taurens onto each others is like putting a multiboxer sign that is visible over the whole battleground.

The main advantage i can get is to NOT be spotted early.

If im allowed to dps freely i can kill 5-6 players in less then 15 seconds EASY (unless they use immunities wich in most cases they wont since they never see it comming)

Imagine hiding 4 gnome shamans in bushes!! :S
