Therefore, no one's is. Stop complaining. Stop whining. If you get beat by a particular character, train against that character. If you are unable to handle spammers, train against spammers. Lose, learn, get better. Stop complaining. Stop trying to say someone else's main needs to be nerfed. Get better with yours. Put in that time and effort or stop playing. Learn your weaknesses. Learn your opponents'. Attack, lose, change tactics. Get better. Stop trying to make everyone else worse.
Tweaking needs to be made for balance issues, the team is aware and are doing things fair and accordingly as a good QA team should.
"OMG SLY NEEDS TO BE NEEEERRREFFFFEEEDDD!"
Not what I would call a legitimate balance issue.
Point: I wish people would call their own skill in to question before complaining about balance issues. Point: Sometimes someone is just better than you. I am tired of everyone with a keyboard complaining because they got beat. Point: Maybe you do have a legitimate complaint. If you do, odds are they will be addressed. I'm impressed by Superbot's loyalty. They are patching the game and working out kinks. Your concerns are being addressed. Point: I'm not saying "Suck it up, losers." I'm saying that other people aren't going to get worse. You'll just have to get better. Skill takes work. The characters are getting balanced. Which brings me to my final point. Until that time...
The game is not that old. If being good at the game is important enough for you to complain about "balance issues", compensate by getting better. That's all I'm saying.
