The changes to the Shaman and Warlock to let them move over water, and let Warlock cloak any unit instead of themselves is interesting. There are now effectively five Naval units. Juggernauts laying siege to a base backed up by a group of Shamans is a scary sight.
No longer are Ironclads (and maybe Kamikaze Transports) the only counter to Ironclads. Warlocks can't be targeted by the Ironclad's torpedoes, but have two abilities useful against them.
The Dragon has a few auras that boost troops. It also has Chameleon Hide so it can avoid being targeted. Maybe relying on that and auras would be an intersting combo. The cooldown on the Dragon cloak is only 15 seconds, so if you have to do some thing quick, you can probably get back under soon.
