OK, here it is. First time a hatched with a hydra I got a death oni. A pet that is supposed to be a hybrid of Helephant (as I have read on other forums) Every attempt since then has yielded another wraith. To this point in time in history I have 15 wraiths. (10 consecutive) What's the deal? The prices on hatching get lowered and the odds of a hybrid get lowered too? If anything has aggrivated me enough to quit this game, this is it.
Hatching at this point and time has made the bottom of the fun list, it used to be on top.
Odds for a Hybrid when Hatching two L-48 pets is less than 50%. Which means less than 50 successes out of 100 tries.
Odds of getting the same pet is a bit higher than 25%. Which means a bit more than 25 times out of 100 Hatches. And -with really bad luck- allows for the possibility of getting the same pet 25 times in a row.
