nah dude GW can take on anyone that doesnt have the range or priority that he does. he gets ***** by people like marth, ike, and DDD, but against people like ness, mario, luigi, the space animals (ive argued my point about the spacees in a different GW thread, but my consensus is hes advantageous against falco, slightly disadvantageous against wolf, and even with fox), and other generally low ranged characters. i know people have sour relations with him from melee, but the real problems he had in melee, such as not functioning like a normal character (little shield, cant l cancel certain aerials), not having approach options, limited mobility, and few pressure escaping options, have all been adressed and given considerable buffs.
but i will defitely agree that everyone did get a lot better, and regardless of who IS at the bottom, the gap between that bottom person and the top person is much lower, and they are still competitively viable and not at much of a disadvantage.
