Ah, scissor kick. I love that move. I did it to Taki in a dungeon, and the ring was iced over so it sent her flying off the ring.
Meh, there is some strategy in SC2. Again, I will use an iced-over ring for example. I'm Talim, and I'm fighting Cassandra. We both keep running towards each other, attack, and change our course so that we weren't getting anywhere. We must've kept this up for half the time limit, at least. Finally I'm like "wait, I'll just stand here, wait for her to come to me, and whack her." So I stood in the center, and she ran towards me, and the AI for her was pretty stupid because she did an attack before she got to me, so then I just did the basic horizontal attack and she slid off into the abyss.
Sooo, that is sort of startegy, even though it's kinda simple. And in my opinion, Marvel Vs. Capcom 2 is more button mashing than SC2.
