Here’s my analysis on Inari:
Even though she is the second 5* I ever pulled, I still have her at 3-70 because I quickly found her to be underwhelming.
Compare her ability which effectively decreases enemy special damage by 56% at average speed to Kadilen who reduces it by 74% at fast speed. And Kadilen has significantly more defense, ensuring her ability goes off. Obviously Inari’s effect is stronger because it affects non-damage too but let’s be honest: damage is the most common and relevant effect in the game. Kadilen is good but not overpowered, which helps give some context to why Inari feels underpowered.
As already noted, Inari’s bad on defense. That’s fine.
She’s bad on offense because she a) Is likely to die before you get her ability off, b) if you do manage to fire it, there’s a high chance it will end before it does anything, so c) you need to wait for the right time to fire it, increasing the chance that she’ll die first (point A again), and d) even if the enemies attack into her ability, there’s a reasonable chance it will do little to nothing. Finally, e) her minions die so easily.
A lot of these problems also apply against titans.
Inari has the dubious distinction of having an ability that literary does nothing if the enemy has certain teams, which is increasingly likely as the fight goes on.
Similarly, though not super relevant, this hero also has the added distinction of having an ability that literary does nothing before you get to the boss in world fights.
The result is a hero that often underwhelming even in her strongest situations, downright bad in others, and on top of that frequently irrelevant and boring.
I don’t think she’s actually that weak but her weakness combined with her niche relevance combined with her RNG dependence lead to a hero that really disappoints. Thus, having thought about it a lot, I suggest:
a) Modestly increase some combination of her health/defense. This will increase the chance that she’ll actually get her ability off at the right time instead of dying.
b) Have her ability actually give one or more characters fox minions at activation, as this will ensure that at least her ability accomplishes something.
All this would obviously need to be tested for balance.
