Not sure if this is a flaw, but secondary and hidden abilities seem a lot more common than they used to be. I wouldn't mind if the rate was every 3 or so Pokemon, but the rate seems almost broken. I searched for a simple pick-up Zigzagoon for over an hour (sped-up, mind you) with no luck. Thankfully Teddursa has Pick-up as a secondary ability, and I found one with no problem. However now I am trying to breed a Skrelp that has Poison Touch... And have had no luck. Something I also noticed was that hidden abilities seem to leak through to the offspring of 2 non-HA parents. Hopefully this is a bloodline concept (which would be interesting), but I'm at my wits end trying to figure this out.
To the creator, don't get me wrong; I really* adore playing Renev so far. My friends and I have merrily played together since Theta Emerald EX. Thank you for all of the hard work you've poured into these projects, it really shows and makes them incredibly enjoyable.
Edit: I just noticed that one of my Pokemon's abilities changed from a normal ability to a hidden ability. Something tells me this is a bug... Just putting it here for reference.
