Hello,
I participated in the world spawn event today on the gold server and was offered a mysterious ticket. I encountered a hidden ability goodra (!!!). It used outrage on my false swiper, which caused confusion on itself. I was not able to catch it because its self-inflicted damage from confusion after outrage killed itself.
I'm guessing there's no way I can prove this or get another shot at a goodra... but if rare pokemon are going to be offered in the world event, the participants would like to be able to catch their reward. My suggestion is to remove any self-damaging moves for all potential reward.
Thanks!
