I'm so glad teambuilder adjusts the matchmaking when I try a new champ

them ward counts though

That is some terrible warding lol. Hell, I'm bronze 3 and I ward better than those people in diamond. Of course, thats teambuilder so they might just not care.... but... eh

I think you should be more concerned that in TEAM BUILDING you allowed a Support Singed with a Volibear Bot lane....

Matchmaking is actually worse when the adjustment is active because high ranked players don't do teambuilder much so most games they do will be with the adjustment. It's still pretty bad without the adjustment because ranked MMR and normals MMR are different. I'm pretty sure teambuilder, blind pick, and normal draft all have different MMRs too.
