I totally agree with you in the left and right allocations that brings the possibility of the specific dragons you want; nobody actually believes me as they kept saying it doesn't matter.
I tried breeding in different side and the possibility are within the few. I came to believe there's a 'lucky' spot (breeding den) & the left/right allocation when i got my diamond dragon!
There's this spot in my dragon place where it always 'glitters' and i put my breeding den there to try breeding what i want, surprisingly most of them works! (of cos i wouldn't say 100% because you need luck somehow)
My diamond dragon was successful after the 3th try with Firestorm (Left) + Island (Right) epic lvl.
It's funny because TL themselves said somewhere that the side's we put dragons on doesn't matter.... I sort of think it does too lol. I noticed the most when I did charm/winter then switched it up with the winter/charm.
I just got a Charm egg and I wanted to breed a Forestfire with Magic, does anybody know what dragon that would make?
So I have come to the conclusion that if u want to get the really rare dragons u should try for them as soon as newer dragons are released! I just got dream, ice cream, hypnotic, and night dragon all within 2 tries the last 2 days! I have 2 other accounts and also got dream, ice cream, & night on those as well! Anyone else getting rare dragons really easy when new dragons are released?
I just got clown although I was hoping for Seabreeze . . . We'll see what the next breeding produces.
