Omitting RM countering Jackson seems dubious (not to mention other important cards; Ash, Jeeves, Batty, Sandburg, etc.). The problem with RM is the opposite of what’s stated; it’s too broad. If it was just a counter to Caprice, it would be fine (or at least better).
And, continuing on that train of thought, the fact that it so heavily affects such cards is very problematic to the games design. Hard counters are always bad design. Hard counters that counter a broad card pool (some of which were problems, some of which aren’t) is abysmal.
Even neglecting the competitive game, RM should not be in the game. Within the competitive game, RM definitely should not be in the game.
Similarly, and perhaps an even better example on this front, Sifr invalidates the strategy of “using ICE”. It is not something that should have ever been introduced into the card pool.
I also don’t think scarcity alone would prevent RM; SoT and Déjà Vu both exist. In general, runner will have an easier time sticking a current in play than you if they’re playing a proper deck (and if I’m playing against Palana, I’m definitely aiming to keep that current in play).
