The game feels to easy.

I started playing the game yesterday and i didn´t lost a single match from 31.
I see nearly only PS4 Player maybey i have a huge advantage because i play on pc.
Or i am to good because i played  moba games for 7 years already?
 
And also i dont understand how i didn´t skipped alot of ranks.
I just skipped 2 ranks by a winstreak of 31.
