Do you often evolve every single Pokemon or are there some in the past that you have kept without evolving them?
Of course there are bonuses to evolution, but perhaps you have a personal reason for stopping it?
When I was younger I often focused on the looks of my Pokemon a lot and didn't actually like their attractiveness as some of them evolved; as a child, that kind of thing was important to me. Now I'm an adult I tend to look at their stats and the moves available - which takes precedence. There is a certain amount of thought and consideration that can go into the process though - whether you've grown attached to a specific one or not.
