Every rank is “literally unplayable” until you reach at least Diamond 2. I say this as a Platinum. 
Considering as a Silver you can now be playing with someone in Bronze or Gold, or Platinum, due to how they allow players to group, you’re probably almost never just in “Silver”.
I hardly ever as a Plat get a game where it’s just Plat’s vs Plat’s, it’s almost always a mix of ranks. To make the game more playable, I suggest you team up, solo won’t be a great experience unless you’re much more skilled than your current rank.
