I always wondered why there is no way to reduce the adraline rush level of your toons. The best way is not to level it but certain toons were usable in the def and off as well so you had to choose. Best examples shields. Nowadays they are pretty much useless (like most other 5*) but you can still use 5* in territory, farming, sr but with the maxed ar it takes more time than needed or shield less than you want it. (I know you can use trainers for faster farming but I prefer it more stable.)
