@protoaddict Sure. Force of Will is "the glue that holds the format together." Nobody is accusing Lurrus of too effectively keeping the opponent's broken T1 plays in check.
Restrict Force of Will (and Force of Negation, now) and you have a format of combo decks competing against each other for who can most consistently get the T1 or even T0 win. Sounds like fun----for one or two matches.
@vaughnbros Setting aside the fact that the top decks currently in the format are combo decks---which combo decks are being "held back"? Combo decks combat Force of Will either with hand disruption (Thoughtseize), on-board countermeasures (Defense Grid), or their own countermagic (Pact of Negation et al.). Countermagic is a necessary speedbump keeping combo decks in check, not some bogeyman preventing combo from thriving in the format. (I do agree that Mental Misstep used to inhibit use of Dark Ritual too severely.)
