No it's different from RR and PF
YS being static means that a match plays out normally, two players fighting like two players would on any stage. Because of that things like shine combos from falco will happen, maybe a little Dair tech chase Dair shine waveland shine Dair off the right side. However when you do it this time, Randal is over there and suddenly the death combo you just did didnt kill. Now obviously since it's NOT random what you should have done is teleported your opponent to the other side of the screen since you knew Randall wouldnt be there.
Only you cant do that, and more so in a fast paced game it's not easy to, mid combo, check the clock to make sure that your combo isnt suddenly going to become moot because of a ****ing cloud. The random element has nothing to do with Randall, but rather the fact that where you happen to land w/e first hit IS random, you have no ability to control where and when you take control of the match to work around Randall.
