^ that last sentence precisely.
But the beauty of balancing a game with the highest skill in mind, is that in theory one can always overcome something by learning more.
Ganon has pitiful grab range, and range in general compared to other heavy hitters such as Charizard or Ike, both of which possess greater mobility and possibly even speed. If he were problem, you would hear about it in the social thread....
Also... what do you mean by:
"he can practically beat over so many people attacks"
are you talking about priority? Ganon's fair is beastly, but again, against a sword, he is outranged, and against projectiles, he is forced to approach ever so slowly and obviously.
If you wish to complain about a character, I highly recommend talking about the character you use against him/her. Match ups vary so much in smash, so perhaps you are just struggling with your own character's weaknesses.
