Everything in the game does too much damage. Most characters can be killed in 2 meters (which are easily built mid combo) by half the cast. 3 is guarunteed death. An across the board reduction is needed and most people agree.
The problem here is that while you're nerfing the characters who do high damage, you are also nerfing the characters that do low damage. Ghost Rider and Hsien-Ko don't do enough damage as it is and you want to nerf their damage output even more?
I'm not saying that some characters shouldn't have their damage nerfed, but it should not be blanketed across the whole cast.
Invincible Turnabout assists almost made him worth using, lol.
In his current form, this is true. Which is why we are buffing him with other things so he would be more worth using outside of Turnabout Mode. The proposed list of changes we have only has one (admittedly substantial) buff to Turnabout Mode, with most of the buffs going into Trial Mode.
Bad evidence is 100% essential given the nature of his design and faithfulness to the source material. It's also probably why this character can never be good. He simply has both 3 things are are awful to balance in fighters
=Kind of a joke character (he's obviously here for comedy)
= pure luck based specials (this never, never works in competitive play)
= a design where the character starts shitty and if X conditions are met, becomes GDLK (ala Phoenix and Frank)
Bad evidence pretty much contradicts the source material. Not a single piece of evidence in any of his games goes unused. There is no "bad evidence" in the world of Ace Attorney, which is why I'm baffled as to why Capcom included such an awful mechanic. As for your points:
-He's not a joke character, he's a comedic character. They would not give a joke character Turnabout Mode and a great set of specials and hypers. I really don't understand why some people say this.
-Luck-based specials? What are you talking about? Besides the trajectory of his Folder and Cell Phone projectiles, he has nothing luck-based about his specials. Well, unless you are talking about evidence gathering, which is why we're trying to make it have as little an impact as possible, and thus my proposal for getting rid of bad evidence.
-And both of those characters are around the high-mid tier area, possibly even high-tier. Who's to say that Wright can't join them?
Give him some small buffs, make turnabout slightly less brain dead, call it a day. The design itself strongly indicates this character can't be good.
I disagree here. It's actually very possible to buff him too much and make him totally broken. I would definitely not disregard a character's design like that.
Small buffs are definitely not what a character everyone considers to be bottom 5 needs. Small buffs are what Hsien-Ko got going into Ultimate and she's still awful.
