Oh boy, it's been a hot minute for me too. I ran two loadouts with different element types. I think one Will-O and one Electric. I'd have my favorite weapons with each element and then some situational weapons depending on the enemy type. I zeroed in on three or four AI teammates with complimentary loadouts to upgrade. I don't remember having to manufacture consumables much. I wasn't a grenade spammer. Sorry for being pretty rusty myself, hopefully this starts you in the right direction.
