I play a defensive stance Thunderslam (actually only the Lightning Blade part) tank and it gives me all the feel of an enhancement shaman tank.

You can use Reckoning and Unfair Advantage to get in more attacks that would generate more Maelstrom stacks. With Righteous Fury, you can have the Divinity talent so you have more healing. You can do Sheath of Light for more nature healing as well even though the capstone is holy focused.

An epic enchant that made Healing Wave work with Maelstrom instead of just lesser healing wave would let you utilize Earth's Blessing enchant but you get into problems when your healer is using Earth Shield since it only adds stacks to yours and theirs is more powerful and would overwrite yours. It would also be really powerful due to the Low Tide legendary enchant which is why I don't think it would be implemented.

Today you can use Lesser Healing Wave with Maelstrom Weapon and the Frugal Disposition enchant and try to get LHW crits to trigger Ancestral Healing (and you may as well go all the way and get Ancestral Awaking too). If you are using Mending Tide for your legendary enchant and Water Shield and a water elemental healing you should feel very water oriented.
