PROBLEM 1: HP DRAIN BALANCING
The hp drain on the following difficulty (Fibzero's Cracked) (Insane) (Banger)
Can be changed from (7.5 - 5) (6.5 - 5.5) (6.5 - 6)
Its hp drain is too high considering its star rating.
PROBLEM 2: APPROACH RATE BALANCING
The AR Of the following Difficulty:
Fibzero's Cracked to Banger (3 Subs)
Should be changed from:
{ 9 - 7.5 } { 9 - 8 } { 9 - 8.5 }
The AR of those 3 maps are too high "Again" considering its star rating.
You could also still lower the AR on the higher diffs as it could be more balanced.
Overall Conclusion: You should focus on the Different stats of the 5 difficulties
to balance Them as it doesnt correspond with its proper star rating.
BUT! Please also think before changing everything if my suggestions are good for your maps.
Only the top difficulty may have a custom name, or custom names for all top difficulties should be used for consistency. I would advice renaming "Cracked" to "Hyper" as a diff between hard and insane
