Willthere be any change/compensation for those of us who have already hit level 183 on champion 3* characters that have the new linked 4* character?
Why would there be?
What he said.
They’ve never grandfathered anything when they’ve changed daily rewards, for instance. I see no reason why they’d do so for champion rewards.
This has already been discussed elsewhere. Please search the forums and read any related threadfs before posting something that has possibly already been asked.
There will likely not be any compensation as nothing wrong has happened. As long as you received the reward that you were supposed to get when you hit the associated level everything worked as intended.
