oh blimey, they've added breed mastery on ZW.
All well and good, but the breeding times for each animal increase with each level. The example given (apparently not accurate very useful then!) is:
"breed times have changed. within each breeding rank, there is a time cycle. for example (not accurate):
bronze rank:
1st animal- 4 hours
2nd animal- 12 hours
3rd animal- 48 hours
4th animal- 96 hours
then, when you start silver rank, your animals will follow the same breed cycle which will reset when you reach gold rank...etc"
hmmm, you end up getting wildlife points, which i can't say I'm fussed about, but if the above is true, it's very boring that the breed time increases with each animal you breed - some of them are long enough already!
