Oh god, this is flattering but the build is giga outdated. Skimming the power stuff it still looks more or less correct to me but you can ignore most, (if not all), of the slotting recommendation as the character building meta has changed significantly since I wrote those guides.
If anyone wants up to date build advice my recommendation would be to ask on the official Homecoming discord, there's a number of reliable build gurus there, including Icesphere who has a dropbox full of builds.
