I use it to surpirse people who take too long on platforms. But now that I hear about punishing aerials I'll look into that too (I usually use Utilt to punish aerials). Maybe we can find out more things to do with this.
And I agree with Katana that not too many people voice their opinion here. And the reason I think this is, is that the people here usually shut down anything they think is "unnecessary". I don't mean to sound rude, but if you look for any past (and even present) Arrow Loop discussion, you'll see that people have generally said "Don't use it. It doesn't work. Period." This doesn't really allow room for growth, and it makes people afraid to post something that MIGHT be usefull because they're afraid of being rejected. I think that this is the Pit boards biggest flaw, and I don't see this flaw in other boards. We need to be more OPEN to new discussion instead of rejecting it if it introduces a topic we don't like (such as Arrow Looping). It's just something I've noticed in the Pit boards. And there might even be people who will be mad at me for posting this. But oh well ^__^.
