The only way to discuss a progression of their original plan is to talk about Classic Plus, really. Back when classes literally had only one viable Raiding spec, one viable PVP spec, and add to that type of design. Modern WoW resembles very little of that original plan, and their choice to balance 36 specs is in the way of adding many new class options.
