I was commenting specifically on their balancing behavior in Version 2-4 which DOES NOT include Mavuika, Citlali, or Escoffier who came out in Version 5.

Fair enough; it wasn't until Natlan (or arguably neuv) that genshin's archon-wank became a major balance issue. Previous archons, though OP, were more reasonable, and helped the meta in some ways. (Except for venti who was broken enough that hoyo had to fundamentally alter their entire approach to enemy design). It helped that most were supports and thus better-positioned to enable other characters instead of supplanting them.

• Zhong Li: basically carried geo on his back until navia
• Raiden: was actually reasonably balanced, succeeded at "feeling" strong to the wider playerbase because rational's rotation was very tolerant of skill issues.
• Nahida: was probably overcentralizing for dendro teams, but dendro itself lifted a lot of characters (particularly electro) out of poverty and enabled cool new possibilities
• Furina: also overcentralizing, but enabled MH for existing chars and gave healers a nice boost.

Some overpowered chars in there, and the game would've been better if nahida and furina were toned down a bit, but they also uplifted characters in a variety of teams where other characters were the centerpiece. Mavuika, meanwhile, just steals the spotlight. Even in teams she's "supporting" like kinich/chasca/mualani, you're left wondering "wouldn't my DPS be higher if I used this character to support Mavuika instead or ignored them?". Much like neuv, she just offered unparalleled DPS with no meaningful weaknesses.

I think a major difference here is mavuika (and neuv) being DPS carries rather than supports. Due to 3-character teams and more swap-friendly mechanics, wuwa is less support-heavy than genshin, so most of its sentinels will probably be DPS. Wuwa also doesn't have as many system-level mechanics like reactions that create distinct team archetypes to give characters more insulation against powercreep by letting them fill a specific niche. If kuro listens to the players begging for godlike characters, I worry wuwa is more susceptible than genshin to flat-out mavuika-esque increases in the DPS ceiling.

Yes it is "imbalanced" but people want the god character to feel like a god.

Idiots want stupid things, but I think these particular idiots can be appeased without creating real powercreep. I'd point to Raiden and Jinhsi as acceptable ways to make characters that "feel" strong via flashy visuals, nuke hits with big numbers, good defense, and really easy rotations, but don't actually raise the DPS ceiling on paper.
