MK is the only character than can realistically "not get grabbed" by a good ICs player, because he doesn't ever have to be on the ground if he doesn't want to.
Not true. Peach does an amazing job of keeping off the ground and away from my grabs.
Toon Link is extremely hard to grab, due to a large amount of his moves auto cancelling, and the fact that he can be holding a bomb at any moment.
I would place a wager that if you watch any elev8 (or any IC's players tbh) match where he lost or "almost got beat" there were spots where he either did a move other than grab where grab would have been better, dropped a CG or allowed his opponent to mash out. (now we've discussed this before and it has been claimed that you can mash out of ICs chaingrab 100% of the time below a certain percent, but until this becomes a standard of the metagame, I'm not sure we can consider it realistic...and this would the only thing that counters ICs, not lol "spacing correctly".
If you always grab, you become extremely predictable. Especially when your grab range is ****ty. Reflex beat the hell out of my ICs for being predictable at Resist 1. It was terrible.
Spacing better WILL make it harder to grab you. If Lucario f-smashes me and I'm not at the edge of his range, I can grab him. Therefore, he should get great at spacing his f-smash, so that it always tips me. Same with Pit's f-smash, Snake's u-tilt, etc.
Do you want to know why Reflex and others can mash out of my grab below a certain percent if I don't buffer it? Because you can buffer mash inputs. If you react quickly enough when you think I'm about to grab you, and start mashing immediately (in the brief few frames before I grab you), then you will break out almost instantly. And when I say almost instantly, I mean if I dash grab you, in the 12 frames where I'm still skidding frmo the dash, you can break free. And by the way, I can show you a hundred videos that have examples of many different people being able to mash out of grabs quickly.
The key is that you have to mash out of the grab at the beginning, or at the end. If an Ice Climbers player knows what they are doing, they will be buffering the grab so that mashing out during the throws is impossible. So you have to get out before I start, or when I stop to try and kill you.
This is brawl, you're going to get grabbed. I watched a set between Ally and Lain from last year, and Ally was doing a good job of mashing out, I dunno if its because Lain was hesitating or because that's just something you can do. either way, THATS why he didn't lose. he's the smartest player int he world, and he still got grabbed, by the Ice climbers, plenty of times.)
Not to poke a hole in your argument, but you just said M2K doesn't really get grabbed. MJG doesn't get grabbed either. (Toon Link) Illmatic doesn't really get grabbed either. (Peach)
Ally is the smartest player in the world because of the same reason that Daigo is the smartest player in the world. When you get as good as the people Ally has to worry about, you assume they are going to execute everything perfectly. So it comes down to mindgames. Ally knows how to use unsafe moves in a way that catches the opponent off guard, and when properly thrown into an otherwise perfect game, gives him the upper hand.
HOWEVER, when you try and use unsafe moves against ICE CLIMBERS, it has a FAR worse risk/reward ratio. His risk against a Diddy Kong is that the Diddy Kong somehow predicts his random move, and gets stage control and perhaps 25%. His reward is great stage control, momentum, and his move connecting. His risk versus Ice Climbers is a prediction -> stock. Reward is maybe 25%. xD That's why he got grabbed. That and, Snake is a fairly ground oriented character, so he's a little more likely to get grabbed than TL or Peach.
There are lots of OP characters in Brawl, but luckily there are enough of them so that tournaments are still moderately diverse and interesting.
This is also the truth. Part of the reason I like Brawl is because of this.
Edit: Forgot Wario. If Wario properly mixes up his approaches, he is extremely difficult to grab. And kills me at like 50% with a damn half waft. ):
