It's pretty hard to find a balance between something beginner friendly VS Blockland's difficult-at-first but mechanically precise scheme.
I dont think Blockland's building scheme was ever difficult for me when I began though. It was fairly simple with a click and place method with an entirely customizable keybind for ghostbrick movement. However more complex tool addons that make building more convenient like the toolgun and duplicator did certainly make things more complicated, most likely because they weren't centrally created.
I very much hope your team considers a legacy 'blockland-like' build method, or at-least some combinations of settings that comes close at the users choice.
