Guild Wars 2

I want to start by saying I am by no means a pro nor near pro player, but as a thief I know my role and I can do it pretty well.
I played my 10 placement matches at the beggining of the season. Won 6, lost 4 so I was placed in silver tier 3. I thought that was a fair placement for me and I was pretty sure I could keep on climbing. Most of my matches, my team mates told me I was a pretty good thief which made me feel even more confident I would climb, some matches I wouldn’t do so well, which is totally fine and normal. So it happened, I started winning more than what I lost. I got pretty fast to gold 1, then the nightmare began. I suddenly started losing waay more than what I would win and just kept on going down and down and down. Now I have 130 matches and I’ve won only 60. I’m in silver 1 and every match i just keep on getting more and more absolutely clueless players who don’t know anything about rotation and surviving more than 5 seconds.
I find it extremely hard to climb because I can’t carry a team by myself and because I lose 20+ rating each time i lost a match and i win only at most 14 rating each time I win.
Ok, so according to this sistem, I’m going down because I don’t belong in silver. But I don’t think so. I’m not saying I should be in legendary or even Platinum, but this is extremely annoying and I’m not enjoying this at all. If I was in Silver 1 but I got good matches with players equally skilled as me, I wouln’t mind, but this? I don’t understand
