I really don't understand the Ness player apologetics train to convince everyone that he's not strong.
"No really guys, we had more representation than any other character in top 64 and a player in top 8, we promise he's bad."
It's genuinely okay for the character to be considered strong. Nobody is buying that Ness players have some super secret inherent talent that makes them outplay every supposed "terrible" matchup they come across. Neither is anyone saying that Ness is overpowered, it's just kinda silly at this point to consider him weak, and I don't really get what there is to be gained by defending such a stance. It also seems their only formula for a bad mu is basically: "They have more range than me" and don't take any other aspect of neutral or punish game into consideration.
Representation is not an indicator of viability. I've broken down how Ness operates time and time again, and how the counter play against him is simple. I've stated earlier that I don't care if Ness is weak/strong. I don't need to rely on updates to validate my wins.
What I would like to point out is that there are A LOT of Ness players. But there are very few that perform at the same level as me, Aki or Stereo. So when players have "Ness experience" what they actually have is PK Fire spam/fair>grab MU experience. I can list all of the unique techs that higher level Ness players use, but you can just watch some sets. This is the reason that Stereo and I don't usually break top 5 at our locals. The last NYC local we both attended, he got 9th and I got 5th. The players we were playing against know Ness. They know that when Ness is hanging on ledge, you crouch just outside of LJC dair distance. You know who didn't know that? Kaos, IPK, SW, Hero of Time, etc. They know that when Ness goes into the air, run up shield covers all of his options that aren't empty landing. IPK learned that in between sets and look at how well it worked out for him. Or what about holding down and in when Ness dash attacks? M2K certainly didn't know that when I tech trapped him with a dash attack>up tilt>jab reset.
But then there are things like how I hit M2K with a bair at the edge of the stage at 100% to win the set, and he survived, because Ness has arguably the worst center stage kill power in the game. He then won with up throw>up air at 90%. Do you know how hard it would have been for me to get another kill set up at that point? All he had to do was circle camp and there was nothing I can do about it. My only options at that point are to CC>dtilt a nair approach but that wouldn't work at my percent, fish for a grab into an up throw>bair conversion, but that may or may not kill depending on positioning, or just space bairs in the neutral. Either way, you're forcing Ness to approach and he has some of the weakest approach options around. If I tried to space a fair, I wouldn't get a follow up off of it. I would have to hard commit to a fair, and if I miss the auto cancel window, I'm dead to up smash OoS, shield grab up throw up air, CC grab, CC up smash..
Or what about how when I played against Mach, and he edge guarded me by down smashing over and over again. If I tried to sweet spot from below, all he would have to do is grab ledge.
Paragon was a great tournament for Ness players, yes. And based on results and representation, you may say that Ness is a good character, but he's really not great. In terms of tier list speculation, he is presumably in the lowest quadrant. However, I like to believe that PM is a very balanced game, and even a character that low can still succeed, although it is difficult. What was experienced at Paragon was solid players playing very well combined with a lack of match up knowledge.
I have a plethora of examples of things that people don't know about Ness because they've never experienced it before, like people who would DI his down throw incorrectly every time (FTR, it's not always in front of him). After sets I was often met with, "Wow, I've never seen Ness do that before." or "How do I avoid this? How do I counter that?" etc. etc.
tl;dr: CC, run up shield, don't get hit by dair, if you do, tech, SDI fair, don't always DI his throw in front of him.
And one last point I would like to bring up, I can't speak for any Ness mains aside from myself, but I'm not saying that Ness is weak attempting to advocate for buffs. I'm stating Ness is weak in terms of tier list speculation. After Stereo lost to IPK we went out to eat and he wasn't saying, "Ness needs an option to deal with run up shield" he said, "What can I do to counter run up shield?" and we had a discussion about it. We're playing the game as it is now.
