I'd rather not right now if that's ok; just don't want all the leaders thinking they can change when they feel like it. Plus I may have to hire a new leader soon to replace Ditto and possibly Omega so I need types open.
There's no rule, I just let them 'cause they have been running ther gyms a long time and well, and honestly I only would have liked to give to one or the other, but they asked at the same time, so I was kinda stuck.
