While Little Mac is easy to pick up, he is REALLY HARD to master and use against advanced opponents.
His strength, speed, and super armor on certain attacks might look "overpowered", but many don't take his awful air-game, garbage-recovery, and lack of projectiles into consideration. All his strength are balanced out by his weaknesses, which is why we don't see him winning that many tournaments, or him placing high on the tier-list.
People who STILL think he is overpowered/unfair just suc- i mean...aren't very good at this game.
And any good Little Mac player deserves respect for winning against strong opponents with such a limited character.
Not to insult/provoke you (especially since you are a fellow Zard-mainer
) but that's entirely your own fault.
Landing the K.O. move is actually pretty difficult if you aren't trying to hit a complete beginner. Its early K.O. potential is a fair trade off for how easy Little Mac is camped, zoned, gimped, and generally killed early and easy.
Not only does the K.O. punch have to be built up (via time/receiving damage), but the move doesn't even have that much of a range. Whiffing the K.O.punch is punishable, and you can even LOOSE the K.O.punch by getting hit a few times/receiving damage/loosing a stock.
-Not that i don't understand your anger though (i myself get really salty over lost online matches XD ).
