Are you serious? Your telling me if you loop an arrow you will confuse m2k and combo him. Looping takes time, you can be punished, if they are offstage returning, depending on where the arrow is you will not get any good effect from it. If you are close to them an looping you will get rushed and *****. You are at a distance hitting the L button kills your entire setup. At a distance where you can *combo* you can get hit or grabbed and the throw or the attack will cancel the attack. The point when hitting someone off is to disadvantage them by position. Than pit can apply good pressure and gimp them, but your saying willingly allow them to return so you can try to *combo* and look pretty-like.
Actually play good people.......
Looping is an AT, and its easier for some people than to others simply put. If your not good at this cause you suck at it, ok don't use it, but don't call it useless either.
Even so if you are pretty good at it, but are a bit not that clever to put it to good use, same thing, don't use it, but don't call it useless either.
Plus there also some other things
1) I've played good people, veryy good, actually... the local champion
2) Your enemy won't always know when your looping that's part of the mind game, is he looping is he looping not?
3) If the opponent is flying away well of course you won't always loop, i'd rather bury him with a rain of semi curved arrows to stop him from coming back, and if he's still doing it, then I'll wing refresh and attack him head on, doing a wall of plain if possible, this works wonders.
4) Looping doesn't take much time, besides when you loop pit can actually move forward therefore looping your arrow against your enemy and shortening the distance, the arrow hits, he's stunned for ab it, and you follow up with a Ftilt.
If he shields, then you Grab.
