Yeeesh. I'm really not someone who complains about little things, but, if true, this seems to be a massive failure on the part of the developers. I can't imagien that playtesters would not discover something like this. Even for games like FF1, I believe, the games endured very extensive playtesting. For a game intended to not only be competitive (in the sense of multiple players competing for victory, not necessarily tournament-level play) but played with strangers online, failing to fix this is, in a word, inexcusable.
I'm fine with the supposedly increased endurance, easy recovery, slower game speed, and other supposed essential, newbie-friendly changes from Melee to Brawl I've been hearing about. But when a mechanic, specifically the homing tether dealy is introduced to make something, tether recovery, easier, but ends up providing an easy, uncircumventable method of preventing that something, someone seriously dropped the ball. By trying to make the game more newbie-friendly, the developers instead ruin a fun mechanic for everyone. That, more than any other problem with the game of which I've heard, is an epic fail.
At least I haven't given up hope that either a workaround will be discovered or the problem will be fixed in subsequent versions of the game. Olimar was one of, if not the most exciting new characters, and I must avoid the abyss of despair until this is confirmed beyond any doubt.
