Cruel campaign it's nice, normal it's too harsh

I'm doing my HC playthrough in 0.2. After reaching act III with my HC huntress, i'm enjoying way more the progression in cruel rather than in normal. I think the numbers in monster HP need to be tuned down in the early game (specially act 2 and 3). The boss fights in act2 and 3 in normal were too long versus them in cruel difficulty.

For example, Jamanra in act2 normal took me to no potions with a HC setup BEFORE the second stage. I needed so desperately an upgrade in my weapon to face him. Cruel difficulty Jamanra was hard (as always) but not this extreme level in normal difficulty.
