Liz does kind of her own unique thing really. In 2.0 there's only 3 tiers really, S/A/B and Liz is in B. There's an 810+ PSR Liz wandering around somewhere in Japan that was on the 2nd place team at a big(204 total players) 3v3 over the weekend. I watched it and she was actually killing people. The character is playable int that version, she's just really not that sustainable due to Matchups. That's how she was in vanilla too, sustainable until she ran into Narukami or Mitsuru.
As much as I make fun of Liz, she was never "oh my god why do you despair" in vanilla, she just had those MUs. Bace was the best Liz in vanilla and was placing very high in tournaments late in that game's life, even over LK sometimes. They ran into Narukami in winners and loser finals at NEC and ended up in 3rd though. Now in 1.1 she is pretty despair mostly due to how she lost the means to do what Persona characters do, and the top tier shitting all over MUs. 1.1 has a cluster of unviable characters for the same reasons though, it's less of a Liz thing and more of a 1.1 meta theory thing.
As much as I like to make fun of characters and be hyperbolic, I will take the time to say the character exists. People tend to forget why characters end up being not used in favor of "wow this character is just trash". There are very few cases where a character just doesn't work, most of the time it's an otherwise fine character who can't keep up with MUs.
Marge and Liz are different with a similar theme. One of them happens to do displacement and neutral better, while Liz still has a very much different gameplan.
