So much stuff needs to be fixed...
Rollback to OB and game is fixed!
But on a serious note...
-Remove damage jumps at 501, 1001, 2001 etc.
-Remove guild mana pots
-NERF NERF NERF Equips and CS gear
-Less stat boosts from Rebirths
-Remove endurance frames (that's what the potion is for)
-Fix stat system
-Less SP boosts from Rebirths
-Solo mode for the storyline, where each room has 1 high HP monster, and it gains HP and damage boosts depending on the level of the player
-More skills for enemies that are able to chain together for combos
-Monsters that require a certain number of air combo hits to kill (So you can spam them for 10 years and still not kill them)
