@ Riot, why does the New Champion Select replace Teambuilder and not Normal Draft Pick?

After all it is a new Version of Draft Pick.

Also did you even remove old Normal Draft Pick over there? (we don't have the new queues in EUW so I cant check) Or do you now actually have two Normal Draft Pick queues, one with the old and one with the new Champ select?

Granted this is your second try at some problems that Teambuilder didn't manage to solve, but that doesn't mean that it is a better version of Teambuilder, it is a completely different approach and actually fails to adress a lot of the issues that Teambuilder does managed to solve, Both have their own merrit.

I think you should keep Teambuilder in Blind Pick and the new Champion select in Draft Pick. That way you don't leave a large part of the community behind.

Edit: you said you have a different version of the New Champion select for blind pick upcomming, but even if that is the case, you should leave Teambuilder in until that is released. New Blind may be a good replacement for Teambuilder but new Draft is not.
