i understand where glyph's coming from, because we can't assume there are enough people in the community to say there is a wide enough variety of players. being broken or above somebody else should only be considered on a character to character basis. while ROB may be generally better then some characters, he's not just flat out better then alot of characters.
you have to assume that what you know, and consequently what i and everyone else knows about what can be done with a character is NOT everything that can be done. it takes a very large community of players to figure out what can and can't be done with a character. and while i think there ARE characters who are flat out better then most, you have to acknowledge the gap between skill level, play style, and matchup.
just because a GOOD ROB PLAYER can be pretty damn good, doesn't mean that it's easy to do or that it's undeserved. you have to take into consideration that if it takes an acceptable amount of skill then its deserved. the only thing that we can determine currently is that from within our community ROB seems really good, and that Lucario seems to be the best.
BUT THERES NO TELLING whether or not someone will come along and pick a character nobody mentioned so far, figure some crazy stuff out, and then become the new best character. based only on the fact that we hadn't seen that it could be done before, that character would have been placed lower. but after someone figures stuff out, it may very well become an S-tier.
the game simply hasn't been out for long enough / doesn't have enough active players (who are on the forums) for us to make a good judgement whether or not someone is just flat out better then another character regardless of skill.
while i do think that lucario is better then most characters flat out, the amount of skill that i PERSONALLY put into play against my playgroup more then accounts for most of the reason he is broken. given i dont even use his grounded side-b or double team very often.
and that just goes to show that we can't accurately judge these things as fact, unless one character is consistently beating another across multiple players. not just one lucario player beating everyone, but multiple lucario players beating out others the majority of the time.
that's what should constitute our judgment of who's "broken" or "OP". while GLYPH'S rob may seem OP, we have no way of determining whether it's attributed to skill and only someone of his calliber would be able to consistently do it, or if most people who just pick up rob can do it.
sorry for the massive post
this is all just my opinion though
EDIT:
i second the rob lucario link and shiek being S tier though. they're definitely the characters i have the most trouble with, and can be totally overwhelming if you don't know the match-up and your opponent well
