It is insulting to have the average player in silver

According to http://www.leagueofgraphs.com/rankings/rank-distribution/na Silver is the median. Ignoring the highest 2 tiers, master and challenger, because they consist of very small amount of people, and they are used to distinguish potential e-sports players; There are 5 tiers, and silver is the second lowest tier; It insults silver players and they cannot say proudly that they are silver because silver is the second lowest tier, not the middle tier; When they actually have the median skill level.

Look at Overwatch's rank distribution. According to https://us.battle.net/forums/en/overwatch/topic/20753625906 The average player is gold. Ignoring the highest 2 tiers (master and grandmaster), there are 5 tiers, and gold is in the middle. So it makes sense.

Edit: What I'm suggesting is to have the average player between high silver and low gold, also naming bronze to 'unranked'. This corresponds to the normal distribution curve which is applicable to most human skills. http://img.tfd.com/mk/D/X2604-D-41.png With 0 standard deviation (SD, which is some skill measurement), as the average. We have: 2.5% of players above 2 SD which are placed diamond and higher 13.5% of players in 1 to 2 SD placed in platinum 34% of players in 0 to 1 SD placed in gold 34% of players in -1 to 0 SD placed in silver and 2.5+13.5=16% of players below -1 SD placed in the lowest tier called unranked (or new player). Since it contains more than 1 SD and cannot be compared with other tiers. And riot doesn't want to make a lower tier than bronze to discourage new players.
