Well, I posted a bug and aparently it was not a bug. The only reason I thought that you could get two heroic dragons per heroic event is that I got two of them last heroic race i did when I got first place. Wasn't aware that it was a bug since the event designs aren't usually informative. Also, Im not the only one who received two heroic dragons as aparent from community FB groups.
Once again, myself and others received TWO heroic dragons from past heroic races. That is, therefore, a bug. A bug that leads to confusion, since there's a lack on specific info on event designs.
I'm definitely not going to be consulting forums for information, in the future, since I'd expect it in the game. I also doubt others will, but feel free to move this post if it supposed to be apart of the heroic race category and not the bug category. Since,obviously, receiving two heroic dragons from a heroic race is standard procedure and not a bug.
