Tweaking the numbers on 20 different skills and monsters was quite complicated. Looking back we should have gone with less numbers to balance. That is why the numbers feel a bit off here and there. We went through multiple iterations of "battles are too long" to "things die with one-shot" until we landed in the current version. Numbers look off, but the length of the battles landed where we wanted.
Your remarks are spot on though, there is a lot to polish still. Thanks for playing our game! :)
