That is something i started doing aswell.
The main benefit that i've seen is messing with the opponents timing (not only reversals).
It helps especially against those who use reversals such as DP's to escape, using the 2k OTG can mess up their timing leaving them vulnerable.
On tech with buttons they'll get beaten by dandy>UP most of the time and you'll be able to connect a c.S with the opponent being in the air and
if that doesn't work you can still do 2K -> 6P
Doing Dandy > YRC is in my opinion not the best choice if you only try to eat inputs.
Against most characters with a reversal you can use it to actually take out the reversal/not-reversal guessing game.
If you time it correctly against Sol you can actually see if he did a reversal DP or not and react to it accordingly.
6P as ender is something that i'll usually avoid.
I see this as something that should be used very rarely because other than the big surprise effect it'll
also not do alot of damage and more importantly let your opponent out of the corner.
Also personally i'll usually avoid combo enders where that is possible (atleast while still playing -sign-).
Some time ago i was looking into just optimizing what i was doing and since then i would rarely use dust during corner combos
aynmore since to me it seemed more efficient to go for shoter combos and then being able to add an air extension at the end.
ex1. (near corner) Starter, K Mappa, RC, 5D, K Pile, K Pile, (5H if possible) 2D
ex2. (near corner) Starter, K Mappa, RC, K Pile, 5H, 2H, jSHD (SKD on lights)
In my mind (atleast for -sign-) the 2nd variant deals more dmg in most cases, is more reliable and sets up oki aswell.
The only reason that i could see for ex1. was stun but without exactly knowing how stun worked i could only see a marginal difference at best.
I'm personally interested in how this will change with Revelator as i see most Slayers using sidedust when possible.
My guess at this point is that anything into 5D, Running H, Running H, K Pile, 5H if possible 2D will be equivalent to
what using double K Pile after Dust is right now. Does anyone have more specifics on that maybe?
