Did you really just say that if people disagree with you, they don't know what they're talking about?
A2, quit looking at things in absolutes. You see every disadvantage as unwinnable, and for you all moves are either safe or worthless. If we were all robots with 1 frame reaction time and every game was played on FD, you would be right, but that's not the game we play. Mindgames are a much bigger deal than you make them out to be, and you want to ignore them because they can't be written out and backed up by evidence. That doesn't mean mindgames don't matter. Kirk got 9th out of over 100 entrants at No Koast v2, where Legan got 17th with Link and Breezy got 25th with Ganon. That's the evidence I look at when I want to see if a character has options.
Most people suck at this game. Myself included.
People like Kirk, Legan, and Breezy are just better than the masses, and few people bother learning matchups for characters that are not considered threats.
There are some disadvantages that can be overcome like a low KO power, low damage output, and in most cases awkward priority is workable, but fundamentally lacking tools to safely create openings is something that must be fixed for the purpose of balance, as the real reason there is imbalance in the first place is because of the unfair distribution of safe methods of killing and creating openings.
I'm not in fact writing out mindgames in my arguments. I'm taking my time to consider what can be done within average reaction time (12 frames) in a match, mixups, bait tricks, and traps included. And of course, I'm trying to see from the perspective of someone who knows the matchup in and out. If I really wanted to go out of my way to ignore all forms of mindgames and trickery and talking about absolutes, there would be no point in arguing tiers.
Ike is unique in that he actually lacks any real mixup, bait trick, or trap with any respectable speed. Besides the fact that he has next to no attacks that can be viably used to approach defenses. All he can really do is spam a lot of Jabs and F-airs, and hope people get tricked a lot into getting hit by whatever else he tries to throw out. Even with his QD buff, there isn't much he can do to approach people that have decent projectiles and/or shieldgrabs.
And seriously, look at Ike's frame data. It's horrible for the most part. No aerial besides B-air comes out faster than frame 13. B-air is 7 frames, but really laggy, and his jump startup is also very slow. His shieldgrab is slower than average at 7 frames, (which does mean he cannot shieldgrab some Jab combos at least), and his tilts are very slow. His Smashes are horribly laggy and he has no legitimate setups into them.
At any rate, it's at least blatantly obvious that Ike is very under par with most of the cast.
PS: You don't know how long I've been trying to prove Inui wrong on everything, and find out that 95% of the time he's been right ever since Brawl's release. The reason I even picked up Ganondorf was to prove to Inui that he was not the worst character in the game.
