Before you jump down my throat with things like "Dude, the game has been out for less than a week." and "Nobody is really the worst, they all have something good about them", let me say this, I know. The point of this thread is not to try to rank some characters higher than others. It is not to ask for buffs on characters that we feel are slightly weaker than others. The point of this thread IS to generate discussion and to learn about characters that we may not have played yet. Doing so will help people in matchups that they might not know much about, or will get people thinking about some apparent flaws in characters as they are today, so we can, as a community try to find ways to overcome them. So please, don't respond with things like "lol, who knows?" or with just a characters name, state why you think they are so weak. Anyway, I'll start.
Kitana in my opinion, is the weakest character in MKX. That may be because I've played her almost exclusively since release, so I know more about her flaws then any other character. Kitana lacks any mixups. She has 1 overhead attack, b2, that has a 23 frame startup and leads to a hard knockdown so you can't get any real damage off of it if you manage to hit it. On top of this she has only a a few quick pokes to punish up close that often are out of range due to pushback, so it is hard to punish up close with her. She also has no wakeup options. her df3 can be armored, but is so negative on block that it is too unsafe to do.
