your Alex was definitely good, wrecked some of my best characters. I play a lot of Ibuki and Makoto and I think you beat both of them more than the other way around. I dunno if I won a round with Ibuki even.
Elena is whack. Her standing roundhouse is like Chun's back fierce except she slides forward. she has a weird hit box too. her roundhouse in general is really good so you can mindlessly standing roundhouse or jump roundhouse and be safe against most people. jumping roundhouse is easy to hit confirm off of as well, so she's extra lame.
speaking of "hit confirms" some of mine were just disastrous. I wish I could say they were all roll back but nah, a good amount of them I watched you block and then activated super anyway. whoops!
