Harmony - Troop Symmetry

That's not quite right! - For example, Dwarves get Specialization 2 through Chaos, and Specialization 1 through Defense and Machines; more details will be in the diagrams.

SRD, did you change the scheme for obtaining Specialization 1?

Please, if possible, post diagrams showing how to obtain Specialization 1 and Specialization 2 for all factions (you can just do it schematically) - for general understanding.
