Following this "logic" could mean you are a noob playing with high rank player into rank 2 too, right?
There is no evidence that you are good...only your teammates carrying you. This is what you said.
Could be yes, tho since i am with many different people highrank, it does not fit here
Evidence can be also watching many games and looking on the k/d and damage and how many wipes etc.
Also a look at the random ranks can help here
And ofc a 1vs1.(As we did years ago on crossing in the woods. you usa, me wehrmacht --> 3 rifles amove in my mg in the middle vp into ragequit

)
But beside this here all, i just wanted to say that your thread title is not correct. that is all
