Rank is nothing now

I'm new to all of this (my 3rd season) and I didn't play ranked at all until the last day of 18, then I played some on 19.  Compared to pubs it seems very hard, mostly because like others mentioned people hold a spot and then use sniper weapons to blast people far away, so you can die anytime and not know why.  Also, there were some matches I did well in and just got a few points added so I had like -43 or so, but then I finished with 30 points once when I didn't do as good, so I don't get what the LP scoring standard is.  I also don't like how you can get negative points, they should cap it at zero. 

My goal is to get to bronze by the end of the season, but I don't think it will be possible so maybe rookie 2 would be a better goal to set.  I too have trouble with random players in ranked for some reason, they do dumb things sometimes like deliberately hot dropping on other squads and getting shot right off the bat.
