This thread deserves to be read by more people – it’s extremely well written and the arguments are logical and compactly presented.
In particular, I imagine these calculations will become a lot more relevant now with the introduction of the ‘Assassin’ stats on gear (Precision, Power, Crit Damage – with Precision as the main stat). This means that players will be able to combine Berserker and Assassin gear to get as close as possible to the golden ratio, as detailed above.
Either way, excellent post!
