These are the sort of justifications for mwl that I think are really bad. Yes, both Caprice and desperado are good cards, but no that is not sufficient reason for them to get banned or mwl.
We saw what impact the mwl had on desperado, and it was basically a 3 influence tax on Criminal. Which can be fine if you want to make Criminal worse for balance reasons, but does not make the other consoles better. The reason other criminal consoles don't see play is because they aren't as good as desperado. Often times with stuff like this it restricts your design space, because decks can include both the old good card and the new card statted to compete with it, but in this case you cannot include multiple consoles. The correct response to desperado is not to restrict it, but instead to say criminal is a faction of strong consoles and design them accordingly. The fact they haven't done so isn't the fault of desperado, but the fault of all the other cards. Finally, and this is the actual most important point, desperado leads to the most interesting gameplay of all the criminal consoles. It encourages a run heavy strategy which should be read as interaction heavy. It encourages lots of interesting ice placement decisions, and it leads to criminal having a very different power curve than the other factions as they're very strong in the early game and weaker when runs aren't cheap. It's a good thing desperado is more powerful than logos or boxe because it is way more interesting. Finally, the other justification for mwl is to balance relative power levels of decks, and I think criminal isn't going to be completely out of whack, and even if it was Aaron or temujin will be far better targets for additional mwling.
Caprice is very similar, yes it will be a good card, and it will probably be part of the best strategy. But Caprice is good because it is the power level needed for decks to score out of remotes given the late game power level of runner econ. It isn't going to displace any runner decks, because glacier decks tend to be way more lenient towards jank because they allow more setup time and rely on ice. Caprice had always had plenty of counterplay because there are so many ways to attack Caprice (econ, ice on remote, other servers). Finally, we don't see glacier decks based around other cards because they simply aren't good enough. Making Caprice worse or banning that isn't going to solve it.
The important takeaway here is that something being good is an incredibly bad justification for mwling, because some stuff is always going to be good and better.
Here are the acceptable reasons for restriction imo:
1. Heavily restricting options on the other side
2. Being so far above the curve it is the only deck people play
3. People really, really hate to play against it
4. Excessive swinginess
Notably 2. Is a deck level justification so it's about deciding what card in a deck fits most into 1. Which I think in both cases is neither desperado or Caprice. Imo 1 is the main concern for balancing, as the goal should be to make plenty of decks viable.
