You have something a little brown on your nose, you should really try wiping it off.
Personally, I'm on the fence when it comes to the cooldown for bosses. I love when I get a Riolu or something like that and I'll just think okay this was totally worth waiting for, but then when you pick up a Charcoal or something from Oak three times in a row...
I wouldn't mind if the cooldowns shifted depending on the prize you get. If it's something like I mentioned then maybe you could battle Oak again in 1 week, but if it's a Pokemon then it'll stick to the 14 day timer.
Agree, i suggested to remove items such as miracle seed, mystic water, but no one dealt with that. Anyway 2weeks is fine as long as the prices will be a little rewarding.
