I have C1 Klee, C0 Yoimiya, C1 Hu Tao, and C1 Diluc. I can animation cancel with Klee, dash cancel with Hu Tao, click one button with Yoimiya, and do basic E A A E with Diluc.

• Klee is high skill, low payoff. Can play harder for 20% better DPS which outdamages Diluc slightly.
• Yoimiya is low skill, consistent payoff. Meaning, you achieve her highest potential most of the time which can never be optimized. Easily outdamages Diluc as they both have the same talent scalings but Yoimiya attacks faster.
• Hu Tao is high skill high payoff. Already good when played suboptimally (exhaust all your stamina), another additional 20% increase when played properly. High ceiling damage.
• Diluc is low skill consistent reward. Has bit of crowd control if used properly and flexible as his kit doesn't expire when switched out to other characters. He is somehow the standard reference of damage for pyro DPS. Consider C4 Xiangling as stronger than Diluc in damage output for same role.
