1) The platform should be bigger when you have to fight a dragon
2) Reduce the number of the cycles with adds
3) Who thought that adds with half a million HP are fun? In arc 5 it is easier and faster to do a cycle with a boss than one with adds. Reduce adds' HP scaling.
Fix the bug where the sets are not active anymore after transformation.
Give us an option to start at the level we want. I dont want to play 3 hours reach arc 5 and go to bed. I have no motivation to do the arena again.
Because I can!
