Kilik is somewhere in top 5.
Top players should be the only ones making a tier list.
Most tier lists are made by a number of members of the community but most tier lists in the end becomed defined by top players as they have more credibality through a number of different factors.
One of those factors most notably is let's say you use Hilde which I see as your first but then I see Ceirnian or KDZ or other top Hilde players who use them a whole lot better than you. It simply means they are more in tune with their character and perform better than you at high level consistently then they hold more merit and their cases are more believable.
Tournament results also are not the defining statistic in tier lists but do hold some merit.
Most tier lists are about the theoretical on paper and less about actual results in reality which is the problem.
What they should be about is a combination of both but more along the lines of reality.
People have difficulty simply because they fail to describe what exactly a tier list is.
Is a tier list a representation of the character with the strongest tools and most effective program to initiate a win?
Is a tier list a representation of the most dominating characters/with human ability in mind?
The reality is most characters if not all, can never be utiilized 100% by a human being...So for that reason we have a significant variable called human error. And with that variable in play we cannot truly assess the strongest character.
However if you wrote a program, that played the game, and utilized each characters options 100% everytime. You might find Cervantes or Yoshimitsu beating out everyone.
Hilde is on the top because a human brain on average cannot process a great enough defense against her. So we say she is the best. For that reason tier lists are baseless opinion driven by human perception.
So then it seems like the best characters, are the ones who can achieve victory for human users with the list amount of effort. The contradiction, is players who can utilize characters that are considered execution heavy and difficult to master, coming to tournaments and dorminating with Rock, Ivy, Yoshie, Cervy, or Mina.
Then we are back to square one.
What I see in some characters is potential, if you give me a character, my goal is to look at the entire movelist and assess how to utilize these tools against another characters tools.
So my conclusion is that the best character in the game is the one with the most amount of options to counter all of his opponents. And with that it isn't even hilde.
Hilde is a cheese character that is completely dependant on the opponents humanity...one mistake and she wins. Outside of that she doesn't have the most options or the best options in the game. But she is considered the top because we are just too human...
