I would like to know why BB decided to change the eggs, is it because of the hoarding and they want to prevent that ?
If so, those are lucky ( and rewarded ) for doing that, while, those who have helped others to get an mma/vet and didn't hoard, can simply look at the shop and wonder if they should stop helping people in the future.
A warning should have been given, or the option to gain some old eggs still. Not like this. It will make people selfish.
Helping guild members acquire a vet or any other item is a huge part of event fun in my guild, i am very disappointed that's gone.
