I’d rather see an option to restart the champion cycle without having to sell the character and having to dump ISO into it to max him/her again.
For example, if you hit max champion level, give an option to restart championing. This could be paid for by hero points, for example 250 HP for 2s, 500 for 3s, 750 for 4s. After that your champion reward ladder is essentialy ‘reset’ to the 1st champion level. Resetting the actual character level is also an option, but I don’t know if I’d prefer that. It could make the decision more interesting, especially in 3 and 4* land.
Advantages:
A reasonable HP outlet
No additional ISO cost
You don’t have to sacrifice a character, or dump HP into temporary roster spots while you re-cover max-championed characters
This would be great. I champed many 2s, but then I ended up selling them after they were maxed, in order to start again. But now I’m using my ISO for 4s instead, so my 2*s sit, fully covered at lv 15.
There have been a number of suggestions for benefits to pulling more covers after you have finished championing a character and upping the iso for selling the additional cover or allowing us to unlock the rewards again seem like the best options to me, the ones that encourage you to sell off a maxed character just seem odd.
