that's more "making the most out of each session", cause this all still took practically 1 hour, even with pulling all those times... plus it's not that hard, pick the gacha, hit skip, rinse and repeat until your inventory gets full. i also have a touchscreen laptop too so it's just a few taps of the screen for me...
plus i managed to spike some weapons to their current max level in the process, along with nearly getting my lv100 huanglong to +99 (i think she's at +97)
maybe it's OCD, but I tend to get the most out of things when I know that it's possible. i enhance with those weapons instead of sell (assuming I get nothing but N and enhancement material weapons, that's about a batch of 70 or more when it fills up, we're talking no less than 700 exp a batch).
besides, it's not how fast you do things, it's how much you get out of it...
