Alright, before we start, let me get one thing clear: This is NOT a rant post. I'm not coming from a rage-quitted match or anything :D I'm in a really good mood, but I'm bored, so I wanted to get some info on balancing that I personally don't understand 
So, I often judge Smash characters too critically. For example, I often find myself to say, for example, that the Villager and Robin is "OP" xD The reason I think this is because, well, I think to myself: "What are their weaknesses?"
Take Villager. Well, he's decent fast, he has great range on his attacks, his attacks are powerful (Dtilt and Utilt...!). He has the slingshot which is really fast, good range and has great knockback. His pocket is like a reflector you can use whenever you want. His Loyd Rocket can be used both as a great recovery, or you can send it out and run inside it. His timber is good if you use it correctly. His recovery is beyond amazing. So... great range, great power, great recovery, decent fast, has the slingshot.. what are his downsides?
And Robin... well, he's slow, yes, but he has a sword which gives him good range to begin with. When he uses the Lewin Sword (or however you spell it, haha!), his areals and smashes get REALLY powerful. He has one of the best Special choices in the game, with Thunder and Arc Fire. He also has a very high recovery, which even is a projectile O.o I mean, with GREAT specials, good range, good recovery and strong attacks - is him being slow his only downside?
Just some examples. Again, please don't take this as a rant post
It's just that I personally don't fully understand balancing on some characters, so if someone could explain for example Villager and Robin, or characters in general, that'd be great! ^^
...By the way,
for life.
