I don't think so.
I was under the impression that once you get to gladiator circuit you qualify to receive the 10k trophy tokens for Uru 3 even if you dont win any more matches. I made it to gladiator circuit and didnt do any matches but I didnt receive Uru 3 rewards. Is this correct?
I don't think so. That's why you didn't get any. You need to have made it to gladiator circuit to get ranked season completion rewards.
