Mavuika is the best character in the game.
No, the title is not rage bait or bias but a genuine statement I believe in and wanted to present for discussion. It has been pretty apparent that Mavuika has had her fair share of controversy, thanks to her design, character, and problems with the writing and structure of Natlan as a whole, which has earned her the title of "most skippable archon". Now this is a valid take as Genshin really is a subjective and personal experience and if you simple don't like a character or their design there really is no reason to pull for them. That being said, I do want to bring up that all things considered, Mavuika really is the best character in Genshin when you consider what she brings to the table as a character, that being her place as a Meta unit and exploration unit.
Mavuika, on paper and in all honesty in practice, is the highest damage dealing character in the game currently. When given her "premium team", she really is head and shoulders over the competition. Mavuika also serves as a very strong sub-dps/support unit for many teams which is a perspective I'm glad to see has shifted since her beta. Now many people dislike her "ties" to Natlan characters and she isn't as "flexible" as other carries but I think this is a bit of an overexaggeration in the community taht has spread. While yes, Mavuika does lose more dps that other top tier carries like Neuvillette and Arlecchino when played with non-optimal teammates, it is true that she is still very much cabable with them. There are multiple videos of Mavuika clearing Abyss with F2P non-natlan teammates and even "flexible" dps like Neuvillette still needs Furina, Xilonen, Citlali for his best teams too. So while Mavuika is more tied to her best teams than other carries, she can clear all the content in the game without them, so her lack of "flexibility" isn't really something that affects players.
Last, but not least, Mavuika, even at C0 is easily the best exploration unit in the game. Her triple tap Jump tech makes her the fastest and furthest traversas exploring unit in the game, alongside her ability to climb, swim and fly. Pair this along with her many exploration techs like being able to jump over ledges while climbing and her climb "super jump" gives her an undisputed spot on any exploration team. Given that exploration and the overworld is probably almost 95% of Genshin Impact's content and time, this is a really underrated part of Mavuika's kit that makes her extremely valuable. Overall, Mavuika provides some of the best DPS, Support Capabilities and Exploration, all in one package that no other character in the game can really match at the moment.
TLDR; Mavuka Top Tier DPS, Top Tier Support and Top Tier Exploration Unit = Best Character In The Game. (Unless you don't like her, then she's the worst ¯\(ツ)/¯ )
