Level 60 Heart with lvl 64 mobs.
Hmmm. Maybe put in the bug forum?
It’s not bugged. It’s bad design or planning.
It could have just been over looked and they didnt notice it. I would still put it in the bug forums.
                                    SAB or RIOT                                
                                
                            You can directly bring it to their attention with a bug report or you can hope your forum post is one of the ones they read. If it was me I would make a bug report.
