Relax. Everyone has a right to their own opinion. I myself was thinking of a higher C but ultimately, by my own judgment, thought it was fair enough to make her a low B. Sure, lots of other B girls are better. But that's my opinion. You may not agree with it. You may not like it. But at the end of the day, it's mine. But that is what voting is about as various people look at different aspects and judge based on their individual personality and perception. So if you personally don't agree with what some people grade, that's fine. But leave it at that. No need to call others out with it. In the end, this is all about fun with a game we all enjoy.
I might as well judge the next girl while I'm on here too. Nerine is another girl I have not had on either side of FKG, but I haven't really seen her as much in helper teams as I did Ino.
Analysis
Starting off with her stats, her HP is pretty disappointing. Having HP at 18700 is not really impressive considering she as an average DEF around 3K. Her highlight is having pretty impressive ATK at 8600 roughly. So while she is not a glass canon precisely, she approaches that level of fragility it seems to me. Her skill is an AOE which is nice considering she is a little better than other at 2.9X DMG.
Now looking at her abilities She has a decent increase ATK of 30% for the team. Increasing skill activation level based upon skill level along with a 15% boost to skill damage is a nice combination to support fully developed teams. She also does a good job for her team by increasing their DEF by 30%, DMG reduction by 5.3% and resist fainting up to 3 times. Not a bad ability there either. But the Achilles heel (ironic pun intended) is her ability to ignore speed altering panels. Which is basically rendered irrelevant come late came. So it is a wasted ability slot. When you look overall at her abilities, she doesn't appear to fit in any specific meta that is favored for team compositions. Her abilities are just common with no specific specialty like Crit or Debuff.
The shortness of the analysis sums up what I think. She doesn't have much going for her. Overall I would initially consider her barely hanging on to a B- on first glance, but those poor stats and wasted ability slot combined with a lack of specialty just brings her down hard to what I have to say makes her C Tier undoubtedly in my opinion.
Waifu judgment
Loli. Automatic F Tier!!!! Nope! Nada! Not gonna happen!
