We judge the character not by their personal output damage but, again, Damage per second. Ayaka holds a 20-tick, 5-second, 300k+ damage short AOE burst. If it lands on 3 targets, like in Floor 12-2-2, that translates to 900K damage, much more if really deep into investments. During this 15 second downtime, her other members or even Ayaka herself can sustain more damage while waiting for the next burst. This is not a luxury for other on-field hyper carries

In your case, if Ayaka does 300K burst, Rosaria does 60K burst, Ayaka does 10k sustaining DPS through normals, and Xingqiu provides 6k sustaining DPS, the overall DPS for 20 sec rotation would be ~27K damage per second. Against 2 enemies, it can reach 47K DPS. 65k for 3 enemies.

Meanwhile Hu Tao doing 40K charge attacks, 8x in 10 seconds, then a 100K burst. During the downtime, Hu Tao must wait for Xingqiu's burst. If Xingqiu's sustaining DPS is also 6K, the overall DPS in 20 seconds is just ~25K. This is also assuming you get 8 Charge Attacks and all are vaped crits including the burst.

For reference:

• My Raiden National reaches 42K damage per second. All bursts align to 15 second rotation. Raiden is just C0.
• My Permafreeze team (Ayaka, Ganyu, Shenhe, Kokomi) reaches 39K damage per second for 1 enemy. 73K damage per second if against 2 enemies. 100K+ damage per second if against 3.
• The unappreciated team Taser does 49K damage for 1 enemy. Leaps to 100K damage per second against 2 enemies due to how electrocharged, swirl, and C2 Beidou burst works.

(Didn't do any complex maths. Just HP of boss enemy in Abyss divide by time taken to delete them)
