Lisa at a good level play? Uuumm, no she is not everywhere lol.
I must run into a Lisa 1/10 games of ranked and pretty often in Lobbys too. She's probably the second most I see represented to Kasumi right now. I might just be getting all the Lisa's though but she has a decent representation from what I've seen.
I need to look at some of Zack's frame data but his main weakness (for my play style) is the loss of force techs. Keeping pressure now is a bitch and being able to PP2KKKK FT for +9 was my go to, follow up with


or



or even



was just a constant stream. Sure he has better strings now but I just can't hold the pressure.


is still a solid entry and



is a hell of an addition for whiff punishing.
I'd have placed Zack at the lower end of mid-tier in DOA5 due to his massive ability to keep offense going. He didn't have Christies complete package but he could keep you on your feet and force guess work and just loop through and through. This is kinda lost in 5U (for everyone pretty much). I mean you can


(KKKK) which I think may be pseudo (need to check numbers) but for me he doesn't have the same re-entry to fight potential that others have right now.
That said!


is legit.


is a monster still.
vs. raw tech you still have a slight advantage to use.
Pseudo-Tech game is a little sloppy as sometimes you'll just raw whiff


and eat a wake up kick.
I'd imagine that


ending strings (




) strings have the potential to be pseudo-force techs. That being the case I'd say he's right up there if you can maintain the pressure.
Until I get some raw lab time, even with his new bits, depending on how FT stuff works out I'll probably leave Zack on the bench. I HAVE to have some way of working the wake up game (be it Ein stepping back and waiting for a whiff to 6P+K or just going in on the tech or Momiji's 7P). It's just the way I feel comfortable.
EDIT ADDITION:
He was low because he lacked tools compared to the rest of the cast and any Parry character ate him as well as strongest strings being high so easily interrupted. But he should have been low-mid overall due to FT and pressure game actually making some of those 4-6's to 5-5's and 3-7's to 4-6.
