people do them wrong a lot. a common misunderstanding is that ledge invulnerability is granted when you drop from the ledge, rather than when you grab the ledge, so the biggest thing that makes LHDL super risky is delaying on the ledge for any period of time. you need to immediately drop and LHDL once you grab the ledge to use the invincibility well.Ok, so this is going to sound very stupid. I expect it to. But no one has explained it to me, and I do fine without it. But Raynex told me once that there was no such thing as a stupid question. So, I'll just ask: Why are ledge hop double lasers supposed to be good? They seem very punishable, and place Falco in the worst of positions. I've been able to just stand at the ledge and react to them, often enough. It could be possible that I've just never seen (as in played against or watched on YT) a Falco use them well, but I find them to be the MOST dangerous risk you could possibly take from the ledge. One that is too risky to be worth using, in my opinion.
But please, by all means, prove me wrong. I want to be educated on this.
that being said, I don't think anyone really thinks they're super duper good anymore. if you're predictable about them, pretty much any character can death punish you with the right full hop aerial.
