In Ragnarok Online, there used to be a system where you can catch some wild monster. After catching it, if you meet certain criteria, it can evolve to a more powerful (and cooler looking) monster.
I was wondering if this system will be implemented in the game or not. This system was the reason why I loved playing RO so much. But, of course, there maybe a reason as to why this can’t be implemented and if so, I’d like to know why.
