Glad to see you're still at it.. I'm not going to pick out times and tell you what you're doing wrong, you're smart enough and a well enough adopted player to learn this yourself..just a few general things to say.
Watching the first match, you really have trouble when someone pressures your shield I believe..if you must roll, roll using the c stick so your shield doesn't leave you vunerable. that being said, you rolled due to panic but I seen many times that you could have simply defended yourself instead of retreating..you lack defensive play using your range..marth can camp..make him try something and act according.
I was starting to doubt you..then around the 2 minute mark, you caused me to smile..not bad..a tad risky but not bad..
Eh, not sweetspotting cost you..work on that..and once again, stop rolling when its unecessary.
Eh, the end disappointed me..but a simple mistake on your part.
As I watch the second video..I see a problem. In both videos, you did many one hitters then left off the pressure and let them simply return at you..mostly in the first vid..why? also, less f-smash when not used in a combo..random ones don't hit.
Your tech chasing needs work, start speeding it up.
Once again, I see a defensive problem..your offensive isn't bad but you don't protect yourself much..and using high jumps is a really bad idea.
Also, I try not to needlessly hop nairs..rather dash dance and slowly close the gap using dash dancing..try to get into that habit. You need to be mixing it up much more.
So start working on your defensive play, camping abit, your spacing will be key in that. Work on following up with a pressure game after those single hitters. small things like killing yourself and not sweetspotting can be worked on later I suppose.
anyway, good luck (if you want me to watch the third, send me a message on yahoo if you have it or want futher help...which you probably won't need with emblem lord on here)
