You are thinking too much Hopefully someone will take their time and answer in more detail, but gameplay is obviously extremely similar: Place totem, cast wind devil, and with inq place seal and with soldier war cry, attack with primal strike and charge up with savagery now and then.

Remember that builds are pretty item dependent in this game, you can’t really talk about builds without also taking into account what items they have.
One of the major reasons I made warder guide was because I think it is the easiest for a beginner to play with since you get so much defenses for free. You can’t really sit and theorycraft hours and hours before you even play the game. Just play it and learn as much as possible. In the end, if you like the game you will make dozens of builds. You will also save some time and such if you are following a guide and will probably make you learn more in the process. You do have an old guide for Elementalist by stupid dragon. You could then just that one together with some devotions and item tips from my warder guide
