Be glad you weren’t there when resin was capped at 120, when weekly bosses didn’t have weekly ap discount, and when dream solvents to convert weekly boss mat to another from the same boss didn’t exist 
.
Just don’t use your resin to convert chonky blue ores to enhancement ores. You can get by with the event rewards and even battle pass rewards for all your enhancement ore needs. You can just use those chonky blue ores as fodder for the weekly parametric transformer, since that saves some ap needed to farm the mats you get from it .
. First thing I did when dream solvents was released tho, was convert every mat I got from boss Childe, to the ones playable Childe needed until I eventually got him triple crowned, same for Zhongli’s case
