Making first time placement matches easier?

[blahrofl]

I decided to start up an alt account and was wondering if I played terribly during my Quick Play games while leveling to 25 to lower my MMR, would I have an easier time getting a higher rank when doing my placement matches for competitive mode?

Unfortunately not. Your hidden MMR from quick play has no effect on the difficulty of placement matches, however, it is indeed one of the determining factors that helps decide where you place on top of how many games you won/loss during your placements, amount of medals, etc. I'm not sure as to how heavily each factor is weighted in the determining process though.
