Well, a little math for the units:
Barracks lv 35 (not fully upgraded - big orc crisis), squad size 2745 (2 non-mandatory ss researched)
11737 units per 3:22 (without using bears)
2348 bonus from Simia
9389 units without Simia
5868,125 units after substraction of 37,5% bonus from Needles
16003,96 units after per 10h
5,83 Squads per 10h
So last event we got 10h of time boosters in 84 chest, which I could trained 14,24% more units (and I'm not counting any bonus from wonders, just clean not fully upgraded barracks).
If I count it with just the Needles bonus (lv 9 - nothing special - that's just 2118 KPs), it's much worse.
And I'm comparing it to the nerfed reward from last event, usualy we could get 32h there.
And of course, we can't choose which units to train as a bonus.
So for the developers: We are not blinded. We are not stupid. We (or our programs) can do math. We can compare. And we can see, when you nerf something. So please stop nerfing!
