L-Canceling helps every character, and if you want to get technical it helps the character with the most lag more. L-Canceling removes half of your air attacks lag when landing, so the more lag you have, the more lag you lose. Marth for example can get by without L-Canceling (Except his dair) because most of his attacks don't have that much lag anyway. Where again, some one like Bowser is much more likely to get punished because all his aerials have so much lag on them.Not true. It helps certain characters, so it does not balance the game, not even in it's base definition. As some said, Marth (on of the top teirs) gets an edge from it.
That part about Roy, is a perfect example of tiers existing at low level play. If everyone looked balanced, then no one character would stand out.However, I have seen characters like Link, Luigi, and Ness do well, and even have an edge over others. It maybe confirmation bias (where you look only for things that confirm your belief). There is also a reason a lot of newer players love Roy.
