Stop Assuming The Skill Level of Unranked Players
Being unranked, by definition, means that there is no hard rank assigned to your skill, and thus does not limit how skilled you can be in any way. I am tired of people just assuming that unranked players are just some tier below bronze, or in bronze itself. Are there unranked player that play like bronze, yes, are there unranked players that play like diamonds, also yes. I admit that it can be hard to determine how good an unranked player is can be difficult as you have no rank to tell you what the ranked history says, but don't just assume that they're all utter garbage.
Granted, people who are unranked because they have yet to hit lvl 30 and are not smurfs are generally bad. Regardless, this is also a bad indicatior because people learn the game at different speeds, some have been playing since season 1 and are still bronze 5, while others can drop into a high rank-level of skill quite quickly. Personally, i'd say it took me levels 15-20 to play at the level of a high bronze.
