This chart is a prime example of how much tippers do mean in general. 6WX thinks Lucina is a +1 for Sonic, and also lists Marth as a +1, but Marth resides in the "easily goes from +1 to -2" area. The fact that both characters are considered to be much the same (+1) shows you that neither character really has much they can do to Sonic to overwhelm him in general, but Marth can essentially put Sonic on a percentage timer.
Example: If Sonic uses Spin Dash into Marth's shield, and jumps straight after (which Sonic usually does), he's forced into a specific range above Marth that can be easily tipped with a jump and Back or Up Air. This essentially means that when Sonic gets to around 100% (even less if Marth has rage), one of his best approach and combo options actually becomes a risk; if Marth manages to shield in time, Sonic can be KO'd. Against Lucina, Sonic doesn't have this worry until he's at around 125-ish %. These kind of things are vital in the Sonic matchup, because with how fast Sonic is, you most likely won't be landing the stray tippers, or the raw Lucina Fsmashes you need. With that in mind, I can understand 6WX's decision. If say, Lucina was less punishable than Marth in the matchup, then I could see her being noticeably better than him for it, but she isn't, and both characters are punished for exactly the same things. Essentially, both characters are punishable in all the same areas, but Marth has something that can be of threat to Sonic, or something that can force him to change his gameplan/playstyle.
On a similar topic, I still feel the gap between Marth and Lucina is a bit much. Like, I understand the reasoning for the gap, but I do feel it should be a little less. I'm glad Lucina isn't shown to be a poor character anymore, because she
really isn't. Less relevant? Maybe, but by no means bad at all.
On another related note, I can also understand the gap between Pit and Dark Pit, and don't see why it seems to trigger a lot of people. Like, Dark Pit has
no reason to be directly next to him. For one, Pit's Palutena's Bow open up far more possibilities and opportunities than Dark Pit's Silver Bow and Electroshock Arm combined. Secondly, Pit has a much bigger playerbase, with players gravitating more towards Pit than Dark Pit (likely because the reasons I stated). Finally, likely because of the last point, Pit has far more results than Dark Pit. So what reason does Dark Pit have to be directly next to Pit? Sure, you can argue that players of the characters should potentially be able to switch between the characters easily, but tier lists aren't about "potential". They are about representation, and results, and reflect the current metagame, and at this time, Pit excels in all of these areas more than Dark Pit.
Luckily for Dark Pit, he likely won't ever be that far away from Pit, like how far away Lucina is from Marth, for example, for the simple reason he is almost 100% the same as Pit. Is he irrelevant? Maybe, but that doesn't make him bad, or will stop him from ever being a few spots away from him in the long run.
(3DS) was incredibly borked and most likely would have dominated the game even more so then meta knght(brawl). The only characters that maybe had a chance at contesting her in the head to head MU was Rosa and Diddy in the 3ds days. Now imagine if they never touched Sheik and allowed for her mains to advance her meta to where it is now? You thought Meta Knight was bad in brawl you haven't seen how OP sheik would have been if lord sakurai would have been merciful. The fact that even after all her nerfs, she still in contention of being the best character in the game, just let that seek in...........
