I think that on average it will be very difficult for awakened logias not to be on atleast YC1 lvl and rather even low top tier.
With that said, Croc imo has more story relevance than Lucci and Kaku and they were brought back awakened aswell.
I'm expecting an environmental transforming ability (sandstorm + turning the ground into sand), with which he can merge (avatar form) and faze through (ridiculous mobility), hakified grand desert espadas from left and right and much, much more...
Logias are the strongest DF type and their awakenings are the last ability to get introduced.
If Croc has it, which I think is a no brainer assumption, he will be a beast imo.
So yeah, he's likely stronger than even YC1s and Doffy.
