@Icewater I explained it in the video description but the short version is that the guy would abuse lag as much as he could and talk shit. Plus he used Turbo too.
To get used to parrying Alex's Shoulder you can go into Parry training mode, and after you set Alex to do a Shoulder you can exit out, go into Parry Training, then after the dummy does the shoulder you can hit select and replay that part over and over.
How Alex uses his Shoulder is exactly how Urien uses his Shoulder in that they're trying to be unpredictable with it. The difference is that 9 times out of 10 that Urien will hitconfirm his shoulder into Aegis and get you in the corner whereas Alex is more likely to use EX in order to get that knock down and control the fight.
I would suggest (and because I main Alex and want no competition
) that Parrying Urien's Shoulder is pretty essential to shutting down his Aegis traps. But just blocking Alex's Shoulder doesn't really leave you at a disadvantage. I mean if you block it, I still have to work at getting back in there, in that time you could jump out or do whatever.
