Personally I feel like its a good thing that a less recognizable ninja in the Narutoverse has a big use in the game, but I stand to believe that Mabui has a bit too much going for her in her kit. Now, most people will point out that they hate the fact that she can give a team 40 chakra in a single round, and 80 chakra on round 2 if you use her mystery. This is mostly because of the dreaded Mabui, Mei, Tenten, Azure Fang lineup, but this isn't about that team. It's about Mabui; some people think Tenten needs the nerf, Azure Fang, Mabui, the whole 9 yards. I won't really touch matters on Tenten other than I think maybe her mystery should have a Battlefield Cooldown of 1 to have players make a more impactful choice between Tenten or Mei's mystery on round 2. But I digress, to me what makes Mabui a bit too strong in my eyes is not only the fact that she can give a team 40+ chakra in a given round, but its also the fact that she can disperse ALL debuffs on a target. Now, you can argue to me that I can quickly dispatch of mabui if I target her and her alone and take her out, which is true to a degree, but usually that'll cost you dearly since you have to make a choice between her or Azure Fang, or whoever else can disperse debuffs as a healer or Breeze Dancer, amongst other ninja, and timing is always key as well of course if you want to counter, so there are a LOT of variables to take into consideration, it's never as simple as just using a blitz team or a team with ignition, because if you're going in arena or SWB you're not always preparing to counter 1 team specifically, atleast most people aren't. Anyway... from the research i've done at looking at all other healers that we have access to in the current NA version of the game, only 2 other ninja disperse of all debuffs on a target, that being Azure Fang (Which is completely fine since she's a main character), and GNW Sakura. As far as I can tell GNW Sakura isn't quite in the meta right now, although I've seen some people use her as a replacement for Sailor Sakura, but GNW Sakura doesn't feel quite as strong as Mabui, well strength wise Sakura wins *Wink, Wink, Nudge, Nudge* anyway, Sakura doesn't quite feel as strong simply because her overall potential is designated around utilizing her Katsuyus with her buff and them overall tanking damage and healing the team. Some can argue this would make her stronger, heal and debuff wise, but I counter-claim since the Katsuyus are generally not that tanky and will only target the lowest life target in your team (not themselves) and disperse the debuffs on that target, and 90% of the time their usually just healing the same person so it somewhat loses purpose and they can be dealt with, with an AoE mystery. That and GNW Sakura has a completely different role than Mabui, sure both are designated healers but Sakura is meant to get in there and deal some damage while healing, while Mabui is an overall buffer. She gives shields, chakra, heals and debuffs, she has a lot more use in more teams than GNW Sakura (depending on the team). Overall I feel as though Mabui shouldn't be able to give BOTH large amounts of chakra AND disperse all debuffs with her healing, instead I think it would be more fair to make it so that she only disperses 2 debuffs at most, this would still keep her in line with the meta, making her still overall useful, and be a nerf in a way where it isn't too much, and lets be honest here, the only other ninja that disperses 2 debuffs is Shizune and nobody is using her (not that I know of). But at the end of the day this is just my opinion and my opinion alone, and i'm a man that spent 20 minutes typing this long winded paragraph that probably won't get read or noticed and i'm sure the few of you reading this will either agree or disagree with me, and i'm not saying Mabui is OP or she can't be dealt with, I would just like to see her toned down a bit where she is still viable and fair. If you're still reading this, than you Sir and/or Madam have a lot of time on your hands and are very patient, so thank you for putting up with this babble and have a good day.
