Enhancement Shaman Tank
This is the 2H tank that I use on A52. It functions well in M+ and feels like an Enhancement Shaman tank.
Legendary: Thunderslam (this is the only DPS-like component and builds the rotation)
Epics: Crackling Thunder for AoE, Imposing Combo works with Lightning Blade, In the Zone for less magic damage
Juggernaut talent allows for Thunderslam to critical on all targets after the charge. This generates the snap threat. All other times, use Lightning Blade.
Rotation is Thunder Clap, Lightning Bolt (instant like a shock), Lightning Blade with Ghostly Strike on Cooldown.
Unlike Stormhammer, you can Thunder Clap away from the mobs, Lightning Bolt then Charge then Thunderslam for the initial pick up.
Static Shock keeps up the Lightning Shield. Mana is not an issue but you can put up a water shield between pulls because it no longer interferes with Earth or Lightning Shield.
