I started to PLAY just after the "update"(couple of months back) .
Imo , after reading the old breeding system it can be summed up as:
Obtain / borrow /(or steal whatever) godly parents, carry a bunch of eggs, and move around kanto hoping it would hatch a godly one.
Now in new breeding system, as mentioned for 100th time, we already know the outcome and hence start with next breeding /EVing right away. In old system if you are a new player, it would take you 50+ eggs to make a fairly strong poke with 31 speed. In new breeding system, you can do the same by catching 30 to 70 pokemon(worst case scenario). You can hunt/vs seek while egg hatches etc so in short you get a more controlled way and saves hell of a time ( if you are new).
The ones who have actually benefited most are old breeders who have(or had) boxes full of breeders and for them, it's fairly easy to create eggs.
For "new" players it's a bit of struggle to create eggs but it indeed is doable and much more fun Imo. Which mmo doesn't have grind? Some mmo have specific levels until you can do quest/Forge weapons etc.
As already mentioned that old system cannot come back ( and if it does, the economy will go down the drain), instead of whining we should suggest the staff for improvements.
I think the breeding system is good enough, but will become better if:
1) confirmed IVs (I hope it comes in next update)
2) alternate money methods(battle Frontier seems good option)
Edit:3)Egg reciving timer. Also Egg hatching and reciving should be based on Game Time and not real time.
Tl;dr:what? It's not even that big. Read it.
And sorry for bad English and typos, written on phone.
