I don't remember saying anything about 'Link's attack options for close quarters'. I'll consider this merely as proof that you didn't read my post properly, which would explain a lot.True, Link's attack options for close quarters aren't really that great, however, that doesn't mean that they aren't bad either. I mean despite the fact that a lot of Link's moves, such as his Smash Attacks & Tilts, have some Lag to them, they all do a decent amount a damage and also have good kill power.
Link's Ftilt, for example, is a good kill move at high percents from around 120% on characters in general. The drawback to this move is that it has a considerate amount of Start-up Lag. But with good timing and precision, you can get this Ftilt to land on the opponent and get possibly get a KO. This is moves becomes move efficient when combined with Perfect Pivoting as Link is able to use his Ftilt to punish his opponent during situations in which the opponent chooses to roll behind him.
And due to the fact that Perfect Pivoting is easier to pull of with Bidou Tech, as stated in the video, you can have a better time at punishing and killing your opponents with Link's Ftilt.
This sort option for Link may even be better than just simply using his Dash Attack for approaching his opponents. Despite the fact that Link's dash attack is also another one of his many kill moves, it does come out significantly slower than Link's Ftilt.
This is one of the many possibilities that Link can potentially perform with Biduo Tech in which I can think of. In my perspective, I think that this Technique can benefit Link in many different way such as strengthening his options to perform mindgames his opponents.
Of course, this will all depend on a player's choice of playstyle as Biduo Tech does require you to reconfigure with the setup of your controller, and at the same time, it takes away some of Link's abilities to perform some his own techniques.
You know what also works for F-tilt? Simply walking then using it, or dashing/running then pivoting it. So tell me, why exactly would I bother with a perfect pivot to get a worse result in the case of dashing/running then pivoting, or a very similar result in the case of simply walking (keeping in mind that Link's walk speed is more comparable to his run speed than most characters)?
I almost get the feeling that you haven't actually tried it with Link yet, otherwise my previous post couldn't possibly have failed to convince you. Have you seen the length of Link's PP? Have you compared it to the likes of Fox or pretty much everyone that used it in the video? You are of course free to do what you like though, just so long as you don't lead others down the wrong path in the process.
