Thank you guys for your answer.
I play in the silver district because, as you said, the gold one is always empty. So every other gold players are doing the same. And I can't go back to the bronze one.
Thing I've noticed in the previous days, about the matchmaking problem, it's not only about the ranks, but the amount of people that are in a group and play against people tagging alone. When I don't play with low ranks like me, we are four players that don't know anyone else in the group playing against four players that are communicating and grouping together. And again, really hard to find the fun in this. I"ve heard a lot about the changements that are about to come on the game, but nobody could tell me the date. So in waiting of that I'm not gonna play anymore I guess, I can't learn anything or have fun when my playtime is resumed in beeing insulted or killed by multiple players all the time.
