You over simplify things, oh with Sheik you just run around looking for ANY MOVE SHE HAS that comes out instantly and has no lag afterward then you just juggle with the simplest combos in the world, or you just downthrow over and over again, oh and at a slightly higher game you can needle cancel into combos too. Wow Sheik is soooo skilled. Man Sheik combos me? I think I'll quit the game, Oh wait falco just has to dair and laser, or Marth just needs to C-stick, OMG Fox can grab u throw UAIR - broken.
ICs are harder to use than those characters, I used to main Marth, ive mained Falco, I am starting to secondary Sheik, the top 7 characters all have something that makes them good, IC make up for having a low grab range and poor aerial abilities for the ability to do MASSIVE damage out of a grab. I think Fox's shine is "gayer" because it makes him difficult to grab even if he just recklessly aerials into your shield, I think the Marth is "homo" because he has a grab range that is longer than Yoshi and amazing ability to punish most characters after a throw, also his tippers and spikes are pretty **** "f4ggy". Sheik is just a boring character to fight or play because her combos are so simple and strait forward, I think skilled players make her look good. Falco is relatively simple to use, just mix up when you attack and when you laser. Falcon's knee anyone?
Anyways all of the top 7 or 8 characters have "gay, cheap, homo, f4gtastic, ********" whatever term you want to use in place of effective moves. ICs just happen to have an infinite, and although easy to perform you can wiggle out before they can do it if you are under 40% and expecting the grab, or if nana is desynched when they grab and you are under 60-80% I believe.
