Developers are in the final stages of balancing, so this is pretty much what you'll see in the final game. The players are professional gamers.
Lisa's tricky moves set her apart. She doesn't simply come straight at you, so if you're not used to her actions, you have no idea what to expect. She also has a lot of strikes with long reach, making her good at mid-range offense, but now she has moves that come from runs and runs that comes from other moves, so she is way more active this time around. Of course you can launch attacks straight from the run, but you can also do things like stop in the middle of the run, trying to bring out a sidestep or hold from your opponent, and then follow up the attack. Her real strength shines when used by a player who is good with this kind of psychological game or has good fighting technique.
