I can confirm the "Legendary Curse", sorta.

The fact that Albino Colocrow is a 4% chance to find, is certainly not true. I found more Noo-Long, Finngriffin and Krash eggs than a Albino Colocrow, which i have 0 from dispite using Pixpet/Pixpet Exclusion Potions on 8 hoards together.
And they are in much less chance to find.

Colocrow is the the way other pit as explained, i had to hatch an egg and hope it will find an egg before it got to a level too high to find it. Its utterly strange.

I would like to say to a Pixpet "dude, i want eggs of rarity X% to Y% only if you find any" but not with a Pixpet Excluding Potion unless it would acually say, when equiped to a Pet, how high/low the range is then, because i have no idea who to calc this. I just threw G100 on my pets because Albino Colocrow is in the lowest as possible chance, which still didnt help getting one.

Many players who were on the hunt for Albino Colocrow are, like me, selling the other legendary eggs for much, much less (i have them on Market for 300PC) to somehow get the funds back they wasted on finding that Albino when i should just have thrown my PC into a bid war instead of using potions that infact cant do anything because its luck based still.

Its frustrating beyond believe as i want to collect all Pixpets and not the same 8 times.

(Sorry for the slight rant here, but the issue of oversaturation and the problem with how the dropchance works is truely annoying)
