I played one game today, and i think that this 40lvl cap and exp system will not work as it is now.
After 28 minutes i have had lvl 40 and got First God.
I liked the system that was made before, a 100 lvl cap was ok.
And:
1. Creeps still give too much experience.
2. Power Books in base (those which give +1 lvl) are too cheap compared to max lvl.
They are now for 2000. It is not enough, supposed to be about 5k per book.
3. Bug one guy told me today.
U can use potions from your Item Stock and they work on heroes!.
