Neither Anka nor Reza need their Ult to be effective — Miho does. Both Anka and Reza rely heavily on their Ult to survive diving, but they can both chip away from the edges of a fight and still jump back in if necessary. In contrast, Miho needs her perk in order to be effective, and she needs her Ult for that.
Also, Anka and Reza don’t have cooldowns comparable to Miho’s. Anka is at 8 seconds and 4 seconds and Reza is at 3 and 10. Miho has 16 seconds on her A (which she needs to combine with her perk to get the crazy performance), and 5 on her B (which roots her, and does pretty low damage).
Miho is much less effective in the gaps between her Ult as compared to those heroes.
If she’s on a good team and they follow through then the gaps won’t matter, but good teams are an anomaly.
Okay, if you have teammates that follow through, then yes, Miho can follow along with the pack and mop up stragglers. She can’t fight enemies who are fighting back though. Any jungler or carry will win a damage race with her, and she won’t do significant damage to tanks.
It’s not that she doesn’t do enough damage, but she is super-squishy without her blink and her perk. Usually if she just disengaged, she would be a free kill if the went back without her cooldowns.
You are mistaken. Her A has a 16 second cooldown.
Reloading her A is iffy (without her Ult).
Her B roots her, so most players don’t take 3 hits from it. It basically hits the same players who stand in Skaarfs burning goop for he duration. 2 are pretty easy to land, and if she uses A she can then get a third which she uses to refresh her A , but if she just disengaged she doesn’t have her A available. Her B does very little damage on its own, and she only has enough focus for the three shots with it.
In practice, the best Miho can usually do while her Ult is on cooldown is to try and connect with at least 2 hits of her B while everyone is distracted, then wait for her A to cooldown so she can hop in and hop out.
Again, if her team is half-competent, then combined with he shock of her initial attack that is plenty because the rest of the team should be following up, but she can’t do anything to carry a bad team.
What WP assassins are you thinking of? Miho does not do assassin levels of damage without her perk and she has no sustain without her perk. If her team is pushing then she can probably move in the middle of the pack, but she’s fragile.
For her to rely on her AA, she’d probably need to build double defense the way that a lot of warriors do, but she’s really best used as a burst damage hero.
She’s just really bad at reengaging, which shouldn’t be a problem with a good team, but if she’s carrying a bad team she’d need to try more than once.
