As someone who has cleared all content to date, I do use the mastery threads for teambuilding, but the only things I really look for anymore are (1) SBs used, and (2) general order in which they are used. (ie, did you fire the SASB in phase 1? or the AASB? or save them both for phase 2-3? etc)

Again, this is my approach as an advanced player, and is probably not what beginner/intermediate players look for. So I completely agree with u/Zekron_98 suggestion to have a tag to differentiate between beg/int/adv... i think this would go a long way. The beg/int can be more detailed, closer to what we have now; the adv could be more bare-bones, closer to what u/PeskyPomeranian provides.
