I guess I can understand the switch back from the Aegis Anchor model to the Golem Model for the water elementals of Lesser Aradoth, but it does present a bit of an issue. Because the golems walk on the bottom of the lakes, instead of hovering over their surface, like they used to, this makes them even less accessible, especially in the larger, deeper southern lake.
If the mechanics that allowed the Anchors to float over the surface of the water could be applied to the golems, the range problems could be decently mitigated, and we've have Golems that could walk on water.
