BANSHI, you're right about one thing. Your post was slightly on topic. The thread isn't "are you a good player," but rather "how do you know when you are a good player." My post before yours explained what I do as a player and why I think I'm of the skill level I'm at. You said you're a champ because you beat a bunch of people in online battle and use vague words in quotes like "top" players. If you're going to go on about this though, fine, you weren't boasting and I misinterpreted your intentions.
However, I'm telling you what's wrong about your logic in determining that you are a good Zamus player. You might very well be a good Zamus player, but playing on WFC is not a good way to find out or prove it. Go to tournaments and place well, record matches and post them online for us to see. Don't tell us that you're good. I'm not bashing you. All I'm doing is telling you that there are flaws in your own logic and making you aware of them and how you're appearing to the community because of them.
I was here for a few years back when I played Melee, and I saw AT LEAST a hundred (this is an understatement) people come through the community claiming they were good. Trust me, I'm being far nicer to you than the welcome that most of those people received. Many of them would argue for a while without having any video proof or tournament results to back them up, and they would often say things that proved how inexperienced they were. Most of them left the community before they went to a tournament because they would constantly claim they were good, the others showed up to tournaments and were proven wrong. To me, and probably the majority of veterans around here, you are no different.
Also, you haven't given any names of "pro" melee players that have lost to people that are new. You still haven't given any names of people from GFAQs that you've beaten either. I'm pretty sure our standards are very different for considering what's good and what's not.
"Pro" players are people that go to big tournaments and place well and receive monetary rewards frequently. Very few people in the US could be considered "Pro" players in Melee, probably around 50 in the entire US (at any given time). Yes, it's true that there might be some kid that comes out of nowhere and blows everyone away like Ken did in Melee, but he's a very unique case as it hasn't happened since. Most new people don't have a grasp for how fighting games work or how mind games work, and without that you can't beat the real "Pro" players because they live off of mind games and their execution, timing, and spacing are so amazing that you'd almost think they're perfect if they didn't make mistakes every now and again in videos and tournaments. I haven't seen newbies take down any of the pros, and haven't heard about such a thing happening. I'm almost positive you're either making stuff up, or your standards are much lower for what a "Pro" actually is. Please, give names.
prinnykurtis summed up how you'll know when you're a good player rather nicely.
One final thing. If you think I'm typing up long posts because I'm sensitive on this subject, you couldn't be farther from the truth. If you actually read a bunch of other threads, I am often quite thorough in my analysis of moves, ATs, matchups, reasons for counter matches, etc. I type up long posts because I care about being thorough, not because I am upset.
