More "Dedicated" Champions

These champions are usually really fun to play because you feel unique and have an actual goal in the game. For example, take Soraka as a very good example. Dedicated Healer. She is fun to play and feels good when you heal people because you know ONLY you can heal that much. They also are easier to learn because you know exactly what you need to do. We need more champions like these because they are fun to play, have clear strengths, and have clear weaknesses. For example, Dedicated Pusher. No doubt would be a threat for structures but where they are good at pushing, direct combat isn't their thing. Can we have more champions like these?
