How do you envision or would like to see the Swamp faction in Heroes of Might and Magic V?

I would like everything to remain as it was in the third game, and instead of the hydra, there should be some kind of Loch Ness monster...:D But seriously, a Swamp Dragon with acid breath.

Acid breath already exists for the Emerald Dragon, and as for the race, we can assume that they worship Shalassa and give them a sea dragon - without breath, but with a couple of other interesting abilities.
