Suggestion for Niantic.

How about just add them into the shop instead of replacing incubators

I prefer good old 10 sweat and bloody km <3

FYI
Most of the garbage in 10k eggs was removed. Now there is a decent chance to get something useful from them. Just today I hatched 2 dratini and a larvitar from 10k eggs.

The problem is that if they cost more than 150 coins, for most players are worthless, since the blue incubators are basically extra hatces, so hatch them faster isn't that useful, if you don't use paid incubators 24/7 (it may only make difference if you plan to hatch the most eggs possible during an event) but for regular use they are basically the same has regular ones, the hatcing speed really matters only for the orange incubator, since you will use it 24/7, faster hatching means more hatched eggs, but for limited uses incubators, regardless of the speed, you will always hatch 3 eggs, that's why most players save them only for 10km eggs, because you can use your limited uses incubators to hatch slower eggs, while hatching faster eggs with the orange one, maybe can be a good thing to put them as a very rare raid reward
