Approaching from the air doesn't mean you're suppose to attack in the air. You approach from the air (ignoring all Pikmins being thrown at you and hoping Olimar has no purple ones), you then land which'll (most likely) force Olimar to use his grab which you can avoid by a quick double jump or a roll. At this point, you'll be at close range.
Why is Olimar being forced to use his grab when you land? Olimar can just put up his shield, which, combining with spotdodging if Ganon decides to use Flame Choke, beats every ground option Ganondorf has. If Ganondorf attacks, he gets shieldgrabbed (unless Ganondorf has moves that he can use on shield which can't be punished this way), if Ganondorf jumps, then Olimar can just space himself to defeat any option Ganondorf has, because Ganondorf can't hit Olimar with a rising aerial and his horizontal mobility is balls.
An Olimar isn't going to be mindgamed into anything because he can beat Ganondorf by doing nothing but waiting and reacting to whatever Ganondorf does.
Also, what does the definitive answer for Rob's BAir do? Essentially, nothing. Rob's BAir puts you in a bad position on shield or powershield. Not only is it frame disadvantage, it's also pushback, and bad positioning. Your in position for FTilt, which you'll also have to shield. You basically go back to where you started again.
If Ganon's definitive to Rob's BAir is shield, then it's not helpful to him in anyway. Rob gets the advantage of BAir on shield.
The ROB boards don't have frame advantages on shield, but since you have that data, show me the numbers. ROB's B-air starts on frame 11 and ends on frame 43 (I think it's 43, the ROB boards have conflicting numbers), so if you can prove numerically that B-air gives ROB frame advantage on shield, then that settles it.
Otherwise, whether ROB is at a positional advantage depends on where it was compared to Ganon when it uses B-air. Are we talking about really close up, like Ganon's grab range, or at the furthest spacing of ROB's B-air. I've been assuming ROB is spacing its B-air optimally because Ganondorf never wants to get really close against ROB, or any character.
Ever heard of spacing? Rob can move NAir back at the start of the move, and then go in. Ganon can't beat it in priority.
If the Ganondorf player knows that ROB he's not going to be able to hit ROB before N-air's hitbox comes out, then he's not going to challenge it. He's going to shield it and see what ROB does before attempting to hit him. ROB's N-air isn't fast enough so that ROB can use it without Ganondorf being able to react to it somehow.
I was comparing it to Olimar's Pikmin the whole time. Shielding is a bad thing if your forced to do it frequently and at such ranges. Yes it can help you out, but it gives the opponent the advantage more so then Ganon, especially if the opponent can force it at any range.
The main point is you're being put at a disadvantage at all times by having to dodge so frequently. Rob doesn't want to reach Ganon till kill percent, so I don't see how it not reaching you is bad.
So what if you're being forced to shield and dodge frequently? If you have enough time to react to each individual projectile, then it's assumed that you have successfully shielded/dodged every single one of them. Being forced to shield or dodge is only a bad thing if you either don't have enough time to react to the projectile, forcing you to dodge pre-emptively, or if the opposing character can follow up on his projectile and punish you for shielding/dodging. ROB can't do either.
It's not what Rob's projectiles can do at CQC, rather what BAir allows them to do.
ROB's B-air doesn't allow its projectiles to do anything. ROB's projectiles are slow enough that they can be avoided on reaction, and B-air does nothing to help that. Even if Ganon gets hit by B-air, all that happens is that the battle shifts back from close-range to far-range combat, where at the highest levels of play, no one has the advantage since Ganondorf can avoid all of ROB's projectiles on reaction.
Being far away puts you in danger of going off stage. You'd always want to be in the air or on platforms when Rob has a projectile in his hand. Even then, Rob can laser to hit you down.
If you're far enough away, all of ROB's options when it has a gyro in its hand can be neutralized on reaction. You want to be far enough away that you can powershield a glidetossed gyro with ease without ROB being able to punish you for shielding. Also, ROB's not going to hit you with a laser because Ganondorf can avoid lasers on reaction and if you're that far away, you're not going to make any unnecessary movements that would prevent Ganon from being able to do so.
Ganon still has to approach to hit Rob. Gyro makes his already limited options more limited.
With a projectile, Ganondorf doesn't have to approach, because he now actually has a far-range option that he can use. With glide-tossing, Ganondorf is more mobile on the ground with a projectile than without, and that alone will help him. This doesn't even include the traps that a character can now set with a projectile in hand.
And I've always wondered why you act like such a coward when it comes to using Ganon in his tougher match-ups while being, what seems like, positive.
As much as I want to win, the real reason I'm a competitive smasher is because it's fun, and when certain characters can use one option and beat EVERYTHING Ganon can do (Falco- lasers and running away with side-B, Sheik- F-tilt and chain, ICs- shieldgrabbing, Olimar- playing by reacting), the matchup goes from "HEY, it's a long-shot, but I will do everything I can to win this matchup," to "wow, this simply is not fun... at all." Granted, I've used Ganon for more matchups now than I ever have, but until we know of a way that Ganon can get around these options, then I'll start using him in those matchups as well, I'm not bothering, because even if I win, it's only because the opponent was doing it wrong.
Clai, since you like talking about how manly you are; Are you manly enough to go all Ganon in tournaments? It may be smarter for you not to, but that's what's being manly is all about.
There's a difference between being manly and being a moron. If there's any hope of me winning a match-up, regardless of the odds, I'll take the odds, but I'm smart enough to know when the odds are literally zero and generally be right. Just as I'm not going to spam Warlock Punches and Volcano Kicks because I know doing so will lead to defeat, I'm not going to fight a matchup where Ganon has zero, zilch, no chance of winning.
