Same except the Scorpion bit, they all became too predictable, speaking from someone who was low ranked (at least that's how I considered myself, no more than a scrub lord).
I mean, I would hope that playing over 4k matches in that game (mostly as Kitana) would have something to do with anticipating what the spamming Scorpions would do

I had just started college so I had A LOT of free time when I was doing my GEs.
MKX on the other hand....I probably have less than 30 matches on there. I was so excited for it but just dropped it because I was heavily into Bloodborne at the time and I never came back to it.
Now I'm playing Dead or Alive plus Guilty Gear, and Street Fighter V will get added as soon as that's out.
