Average Block Time decreased by 5 sec from 20 down to 15 sec. This is quite much and with low diffi, i get the same amount of eth like before the fork.

LOL and lower diffi -35% ?
Ok you ignore it XD
25% block reduction + 35% lower diffi versus 33% reward reduction, this is what you must compare.
you're missing my point
You are looking at simply earnings
I see a smaller pie, regardless if you are getting the same sized piece of pie.
