In nearly every realistically synergistic team where you're using Escoffier + Yelan the Hydro application is so strong that she is going to be repeatedly wiping the Cryo aura so you're not getting 15% crit rate from Cryo Resonance. This only applies to enemies immune to Frozen or who have drastically lowered Frozen duration(bosses and most local legends) but these are the only enemies that actually matter so you should always be building around the assumption of fighting a boss. The only way around this is if you're running triple Cryo with Yelan as the only Hydro but even then it's only like 40-60% uptime and this suggests you're not using Furina which means you're running a gimped Escoffier team.

Unless you have a hyper invested Shenhe her handful of quills are not going to amount to higher team DPS than a decent Yelan contributing like 30k+ personal DPS.
