The whole Cryo element is basically Chongyun and his harem: ganyu, ayaka, rosaria, eula, aloy. And with future banners coming, Shenhe will join that group too.
Overall, cryo is a pretty average element, but is really boosted by Chongyun, one of the best cryo units in the game. On the other hand, universally hated units like ganyu and ayaka bring down the element, but Qiqi sort of makes up for that loss. Not to mention that ganyu and ayaka are extremely weak and do not synergize well with any character, with all their supports being more efficiently used in other teams. My Kaeya-Rosaria team does way more damage than ganyu and ayaka.
Cryo has a lower damage ceiling than Pyro and Hydro. Cryo can only get 1.5x multipliers from melt whereas both Pyro and Hydro can get 2.0x multipliers. And the crit rate boost is overrated since overstacking crit damage hits diminishing returns fast.
So fuck ganyu and ayaka simps. And Liyue big 3 my ass. Everybody knows Eula and Raiden powercrept ganyu long ago. The flat-chested shorties ganyu and ayaka are not in the same league as Eula or Rosaria in thickness or dps and never will be.
Players are better off using Pyro, Hydro, and Anemo characters for more meta playstyle.
