i think it should be the other way, marksman should be stat bound to crit chance just as juggernauts are stat bound to raw health, it makes designing them easier when they build their intended items (preferably items that don't muddy their weaknesses)
it's part of why yasuo is so tied into his double crit chance, if he wasn't heavily pushed towards building crit he'd build stuff like triforce>steraks>tank and god we don't want that.
crit items generally lack health or defensive stats, and you need to ussually stack 2-3 crit items to make them efficient so there's little room for defensive itemization, this makes champions who are bound to crit innately glass cannons
and with crit they can have strengths in their kit that compensate for being made of glass\
i love my youmouu's black cleaver lucian just as much as the next guy but i understand why it's kinda nuts
just wish BF sword was 1100 gold like dirk, god i love dirk
