Lol yeah i guess hu tao outdmg diluc with deathmatch. Sadge
You don't need math guys or to calculate just to disprove your statement. You only have to have the same characters in the same level artifacts, talents, and char and weapon levels on the similar level and play them yourselves.
Below are the specs of my Diluc and Hu Tao:
Constellations and Levels: C1 Diluc Lv.81, C0 Hu Tao Lv 80
Weapons and Levels: Lv.90 Wolf G., Lv. 90 Jade Winged Spear
Talents Levels: Diluc 8-9-8, Hu Tao 8-8-8
Atk%/Crit rate/Crit Dmg/HP: Diluc(51/144/2745/18.2k), Hutao(88/135/1368/28.9k)
Diluc is still my favorite but damn, Hu Tao is on another level. Btw, I'm using Zhongli so it trivializes her risk vs reward gameplay so I just focus on damage than being safe.
