Frost Wall, Glyph of Dominion and several of the Runic Invocations sound like what you’re talking about here. Even one of the conversion nodes on Runebolt turns it into a turret. Also some of the stuff in Flame Rush has synergistic functionality and theming.
I’m not saying it’s exactly what you’re looking for but there might be something for you in it that you find fun. I hope you enjoy it, and if not, maybe we’ll do better with another upcoming class…
