Did you two not read what I just said? He doesn't get simply gimped that easily without very risk, especially if the Olimar is competent. YoshSSB ate a stock loss in one of his attempts to gimp me. I'm not saying the method of ledge-grab is futile, but it's seriously risky against smart Olimars.
And I'd also like to add that to exploit Olimar's recovery weakness, you have to, oh right, get him off balance first. Good luck with that, because Olimar's on-balance game is OTT even without the Pikmin color tracking, what with generally near-instantaneous if not instantaneous attacks and the ranged grab. HAL thought it would be a good idea to make his general weakness lie in his off-balance game, which only makes sense on paper, but in practice, it's either a Skill Gate Character like Pit, or an exact opposite.
stop complaining about Pit, geez.
Depending on the character you play with, Getting Olimar off balance, and then gimped varies on many levels. But there are always some levels of whcih character, they will have a much easier time then you will let them beleive.
MK, Luigi, Marth, R.O.B., mainly characters with many jumps have an easy time getting Olimar gimped no matter how many mindgames you throw into your recovery, or ways you get around being ledge hogged.
for example: from a certain distance down even with a Purple Pikmin at hand, your attempts to recovery are neigh more than futile. There are options, like Upair for recovery heigjt, and same thing with air dodging, but you own't recover if they have a good recovery, or are just smart enough to use invincibility frames or use common sense and get on the stage, at the correct time where they will be safe from damage and your still dead.
Characters like R.O.B, MK, GnW, ect. can do such amazingly gay/funny things to your recovery that if you were'nt getting gimped by them you might just sit and laugh at it.
Say you've both Double Jumps and your offstage at 40 because you got grabbed by uhhh let's go with D3. He bthrows you off stage. Your off stage at 40 with both double jumps and just by some random luck of their account not yours you get hit with Fair/Bair. You DI the right way and everything, up and toward the stage. You are now in a horrid situation, but you don't realize it. The opponent has multiple jumps, that can lead to you losing a stock off of two hits, you decide to be safe use your other jumps, and to be even more protective you spam whistle!(correctly not all noobish-like.) You make it back to the stage safely, but before you touch the ground you get grabbed again by D3, and thrown off stage. WOW, unless you have some miracle DI(which is possible to Di back from not saying it's an auto - stock loss by any means) but you have an extremely hard time getting back to the stage in a proper fashion, while still worrying about not getting hit, by sime huge rapist penguin, with (compared to yours) god like recovery, and an amazing gimp ability.
Tis is one of the many circumstances, that happen that make people groan.
But also think, Gimping is the MAIN way, to kill Olimar, and the faster people find ways to do this efficiently with their character the worse off we are.
This is what's holding Olimar back.
