Let's take a look at what chinks are saying
>1* I haven't played the game but everyone else is rating it 1* so I'm going to do the same
>1* Nothing to say
>1* The balance is so bad and my class isn't viable (they're talking about a class which is currently among the highest DPS)
The balance actually is bad but I thought it was funny that they used a strong class as an example.
>1* Game runs like shit on my phone
>1* The game has bugs (Doesn't elaborate)
>1* There are no tanks
>1* Bring back the old Blue Protocol (LMAO)
>1* Why am I forced to play with other people in an anime character raising game (I don't think he understands that it's not a gacha)
>1* Piece of shit game (Doesn't elaborate)
>5* Everything about this game is good, as long as you're not an anti-social netizen
>5* The game runs good on PC, don't play it on your phone
>5* The devs work at insane speed and fixed so many bugs already, says that there were some server problems at the start and minor bugs but the dev response and compesnation has been good and the people leaving 1* reviews are whining over nothing (has a bunch of people attacking him in the comments)

Most of the reviews are made by phoneposters, it's clear that they're not used to playing MMOs and most of the PC users left 2-5* reviews.
Chinks seem overly emotional and critical over even the smallest issues, rating 1* whenever they feel slightly inconvenienced or annoyed at something, possibly doing it in an attempt to get more compensation.
