I think it's more important that you gear purple augments and know your class (rotation, keybindings, bosses mechanics,...) that get golden augments. Anyway if you want get golden augments here some tips:
- Get 5/6 chars lvl 80.
- Get 1/2 crafters chars.
- With GSF each week you can get 4.050 tech fragments per char, 5 chars you can get 20.250 Techs, almost 3 OEM/RPM each week. Weekly Time: more or less 12 hours with bad luck.
- With Conquest rewards plus guild reward more Tech Fragments each week.
- With FP and SM ops more Tech Fragments each day.
So each month with a bit of luck and time to play you can craft 1-4 golden augments, but gear golden augm only is interesting for NiM and High PVP.
Best.
