That's why I said that not every hidden ability should be directly copied from b/w. The devs have the unique advantage of being able to know which hidden abilities were broken when implemented because we have a huge history of competitive b/w that can be researched and analyzed. If Speed Boost Blaziken and Contrary Serperior are broken (which they were), give them different abilities that still give them a unique niche in pvp since they don't see much play right now. Flash Fire for Blaziken and Chlorophyll for Serperior, just as an example off the top of my head. Again, I don't think this will be an easy project and it will take some time, but it will make the game a lot more fun and varied I think.
