Wow do people think she's really that overpowered? Yes she has some fantastic pressure but she almost always has to get a counter hit in order to start it. A solid defense is great for preventing her from doing this. She's also got some shit mid-low and high-low strings which really puts her in a poor position up close and has major safety issues now that the majority of the cast can punish her 4f+k, her main tool for shutting down aggressive players. Lisa can also be slow escaped easily and has a crap SS game.
I do agree she could do with some nerfs, her strengths lie in punishing unsafe lows which she gets lots of guaranteed damage, insane juggle damage against lightweights, 1p which is a great counter hit hunting tool since it tracks and has good range (plus her annoying parlor trick 1pk), most of her BT transitions are safe, BT stance is also very solid (BT 1p, BT 4p, BT 7p), CB from front and BT stances which provide unshakable stuns when used in combos, 66pp which gives a potential limbo stun for big damage, she can throw punish very well and 9k mixed in with her spacing tools gives her great oki potential.
A great nerf would be to take away 6f+p, I find that being a shenanigan based character in DOA5, she isn't capitalizing on opponents' holding mistakes with Deja Vu like she used to, her throw punishing game is being taken for granted a lot now that she can do it across the border. I also don't think she needs her limbo stun from 66pp, it's inconsistent yet adds a lot to her already crazy offense. Lastly, I would like to see the immense advantage she gets from 1pk on counter hit reduced, as a tracking string its incredibly rewarding due to it's equally annoying follow-up and the fact that she can do almost anything after she gets the stun. As a counter measure she should have more advantage or less recovery on her 6pp/3p on counter hit, it would make 1pk still a viable tracking tool but easier to react to.
