Boss rush leaderboards have reset due to the following changes
Taking a look at classes' win rate for the last day, it shows Rogue is an overperformer. It's the top selected class with the highest win rate, so I've adjusted some of the cooldowns to hopefully bring it inline with everything else.
Additionally Wizard has been underperforming since the last round of nerfs, while both Druid and Shaman have low win rates.
Fixed an issue in "normal mode" where waves would stop spawning during boss phase. Waves should spawn every 15 seconds again.
There is an issue with the Rat Ball where killing him on the frame he gets promoted to Rat King makes it so you cannot complete the run. While it will take some refactoring to fix the issue there is a temporary fix to end the run if this occurs. **Your score will be less** because we now take boss damage into account, but at least the run will still be scored.
Boss rush can now be toggled on/off from class select screen and on restart level if unlocked.
