(sorry for my english i don't speak english very well)

After the patch 1.2.1.8, the "early game food star system improvements have had their gains reduced". So I checked in wich ways the technology have been, and I notice this about food technologies :

 A tier 2 technology 

A tier 4 technology

A tier 5 technology !

As you can see all those three technology have a similare effect (the tier 4 and tier 5 technology are literrally the same). So even if the food seems to be really powerful in Endless space 2,. In fact, nerf the early game food improvement without rebalance mid and late game improvement (mid and late game improvement that, to me, are clearly bad)  is not a good idea because it will slow down the early game phase for no reason and it will not allow the faction to catch up the late.  

But i didn't play any game since the patch comes out so i don't know if i am right or not about the balance. At least i wanted to show you that a tier 5 technology and a tier 4 technology were exactly the same.
