Each should remain seperate. If you're taking Normals that seriously, you should just play ranked anyway. Normals are for practicing things in a reasonably competitive place. Even with Practice Tool and the laughable Intermediate/Beginner Bots, there are many things you can only work on against other people. Normals and Blinds are the avenues to do that.
This isn't about taking Normals seriously. It's about improving matchmaking. Matchmaking relies on the expectation that once a player has played a significant number of games, they will make only incremental improvements in skill. For the most part (regardless of how badly people whine), the matchmaker is fairly good at this.
The problem arises when a player focuses on Ranked for a large number of games, resulting in a large increase in skill, and then plays a Normal game. As the Normal matchmaker has no idea about the large number of Ranked games played, it will match that with players that are at his skill level before he started playing ranked. This is a less fun experience both for the player and for the opposing team.
