This feels far better to collect loot throughout a season and go on HUGE decoding sprees, all while taking up minimal inventory space, bravo!
As far as core activities are concerned, you really just need to add a decent weapon to gambit. People are using vanguard focusing to get a hothead, crucible to get riptide. Seasonal weapons are a bit lackluster, but you've made good progress with the system it's atop, so I applaud that.
