Don't Worry...
Don't worry - the system I implemented in my TL mod is actually customizable so you can actually even make the game easier if you so desire!
For example, you can even derate the statistics of units if you specify a value less than 1 for the stat increase (I experimented with making easy have a 0.98 modifier so that creatures would have 2% less stats, but I ended up keeping it at 1.0).
I'll probably end up implementing similar scaling factors, here is what I used for The Legend:
Easy: 1.0
Normal: 1.0
Hard: 1.1
Impossible: 1.25
So you can see here, that Easy and Normal were not affected.
There is also another difficulty amplifier I used - based on the map difficulty that is also configurable. In The Legend, the maximum map difficulty level was 100 and so I used these divisors to set an additional map difficulty bonus:
Easy: 50 (100/50 = 2, so 1.02 modifier for Haas battle at the end)
Normal: 20 (100/20 = 5, so 1.05 modifier at end)
Hard: 10 (100/10 = 10, so with 1.1 above, a 1.2 modifier at end)
Impossible: 4 (100/4 = 25, so with 1.25 above, a 1.5 modifier at end)
These are changeable if you so desire to make it easier / harder depending on what kind of game you want to play and so serve as other knobs to twist when playing. What is really neat here is that both of these are independent and can be easily disabled as well.
