If a Shaman has Charmed one of your units, try having a Warlock use "Meet the Beetles" to polymorph it, so your own units will be less likely to target it.
Shamans being able to cross water lets them heal naval units, making Juggernauts even more intimidating.
Warlocks out-range Devastators even in siege mode, making their "Meet the Beetles" or "Death From Above" good ways to remove pesky Devastators from a fight.
The increased Cloak duration and spellcasting range makes Warlocks suitable for a strike team. Their ability to hover over water allows them to approach from different angles. Warlocks can also attack Ironclads without fear of retaliation, being too high for Torpedos, and too low for anti-air.
