Idea for New Champs being Released

Lets have 1-2 week period where they can not be played in ranked but they can be played on normals.

Reason for this:

1- People should have a good understanding of a champion entering ranked, so let people have the oppertunity to practice them in normals and even if they are not bought, people can still practice on free week.

2- Since they are a new champion they may have certain glitches or exploits or maybe they need a buff or a nerf because they are too weak or too over powered.
