In the end views help you grow, subscribers don't necessarily do the same. If someone watches your video they watched it. If someone subscribes they aren't guaranteed to watch the videos. So ultimately you can't grow your channel without views. Although I enjoy watching the number of our subscribers go up. I judge my channel improvement not by subs, but how many views I bring in a month. If I didn't do better than the month before then I need to do something different. It's easy to persuade someone to subscribe... But to encourage someone to watch regularly is a whole different story.
